For a metal fan, the story of Dave Mustaine has always sounded like a revenge plot that kept paying dividends. Metallica fired him in 1983; he answered by founding Megadeth, then outlasted every grudge, every tour, and a stage 1 throat cancer diagnosis — here’s what’s confirmed and what’s still unclear.

Eight rows, one pattern: the public record on Mustaine is firm where it matters — identity, family, and genre — and noticeably looser where money is concerned.

Why did Dave Mustaine quit Metallica?
The short answer: he didn’t quit — the band fired him. Mustaine was Metallica’s lead guitarist from 1981 until 1983, when the band dismissed him over his alcoholism and aggressive behavior, replaced him with Kirk Hammett, and sent him home on a bus (Wikipedia (community encyclopedia)). Within months he founded Megadeth, the band he has fronted ever since.
The 1983 firing explained
- The firing happened before Metallica recorded its debut album, which is why the credits on Kill ‘Em All still carry his name.
- The result, in every telling: Kirk Hammett took over lead guitar.
- The bus ride home became part of the myth, and Megadeth became the rebuttal.
The calendar helps explain the reaction: Mustaine was 19 when he joined and 21 when he was fired — young enough to remember every slight, angry enough to build an entire career on it.
Legal agreements and songwriting credits
- Four songs on Kill ‘Em All list Mustaine as a writer.
- A 1980s settlement ended the financial dispute over those songs.
The implication: the firing was the most generative moment of Mustaine’s career. It stripped him of a band and handed him an identity — every Megadeth release since is, in part, an answer to that morning.
What is Dave Mustaine’s disease?
In 2019, Mustaine was diagnosed with stage 1 throat cancer; Rolling Stone (music magazine) later identified the specific diagnosis as squamous cell carcinoma at the back of his tongue.
Throat cancer diagnosis in 2019
- Mustaine kept working through treatment, recording The Sick, The Dying… And The Dead! during the cancer battle (Megadeth.com.ar (2025 interview archive)).
- He described the battle as successful and said the disease is behind him.
- The memoir In My Darkest Hour details the cancer journey in his own words.
Remission and current health status
- Mustaine declared himself in remission in 2020.
- In 2025, a low-confidence report on Czech Wikipedia noted Dupuytren’s contracture, a hand condition; he can still play guitar, but the condition is progressing (Czech Wikipedia (community encyclopedia)).
The diagnosis that made headlines in 2019 may not be the health story that shapes 2026. Dupuytren’s contracture is progressive, and a farewell tour that demands nightly precision is exactly where a hand condition becomes a set-list problem.
The pattern: Mustaine’s health narrative has shifted from survival to maintenance. The cancer is in remission; the body is the new variable. For musicians, health stories age into legacy stories fast — see Phil Lynott: Death, Children, and Lasting Legacy.
Are James Hetfield and Dave Mustaine friends now?
Cordial, not close — that’s the most accurate public summary. The two men shared the stage at Metallica’s 30th anniversary shows in 2011 (Rolling Stone (music magazine)), ending the coldest phase of their relationship, but neither side has signaled a return to collaboration.
The 30th anniversary reconciliation
- Hetfield and Mustaine performed together at the 2011 shows, a public thaw after decades of competing catalogs.
- No joint tours or formal collaborations have been announced since.
Public statements and performances
- Public statements from both camps stay respectful.
- Interviews suggest the relationship has settled into professional distance.
The Hetfield relationship is the last unresolved chapter of Mustaine’s origin story. A joint tour would be a culture event; its absence is why every interview still asks the question.
The trade-off: fans hoping for a Metallica–Megadeth co-headline can stop waiting. Professional respect after four decades and one legal settlement is its own kind of peace.
Does Dave Mustaine still get royalties from Metallica?
No — the account closed decades ago. Mustaine’s name appears on four songs from Metallica’s debut album Kill ‘Em All, and he reached a settlement with the band in the 1980s over those credits (Wikipedia (community encyclopedia)).
Songwriting credits on Kill ‘Em All
- The four credited songs reflect material written before the firing.
- The credits are historical; they do not generate an ongoing revenue share for Mustaine.
Financial settlement details
- Mustaine received a settlement in the 1980s, closing the financial dispute over his songwriting.
The settlement is why his name stayed attached to the songs while his paycheck did not.
The money question was settled early and cleanly — a contrast with the estate disputes that follow many rock careers, as documented in George Harrison: Death, Net Worth, and Final Words.
The implication: fans who frame the royalties story as an open feud are reading an old headline. The financial relationship ended in the 1980s; the musical relationship has been running on spite converted into output ever since.
What song does Megadeth refuse to play?
The song is Megadeth’s 1987 cover of the Sex Pistols’ Anarchy in the U.K. Mustaine wrote a verse for it that references drugs, and he has stated he will not perform that verse live (Wikipedia (community encyclopedia)).
The 1987 song with drug references
- The controversial verse is Megadeth’s own rewrite, not part of the original Sex Pistols lyrics.
Band policy and performance history
- Megadeth has played the song without the verse, or left it out of setlists entirely.
- The band still plays other Sex Pistols covers.
The pattern: even in a catalog built on provocation, there is a line Mustaine won’t cross in front of an audience — a rare off-switch for the band’s say-anything posture.
Dave Mustaine timeline: from Metallica to the farewell cycle
Seven dates, one storyline: every interruption — the firing, the diagnosis, the farewell announcement — produced another record, another tour, another chapter.
| Year | Event |
|---|---|
| 1981 | Joins Metallica as lead guitarist. |
| 1983 | Fired from Metallica; forms Megadeth shortly after. |
| 1985 | Megadeth releases debut album Killing Is My Business… And Business Is Good! |
| 2011 | Performs with Metallica at their 30th anniversary shows. |
| 2019 | Diagnosed with stage 1 throat cancer. |
| 2020 | Declares himself in remission. |
| 2025 | Publishes memoir In My Darkest Hour. |
Primary reference: career entries as cited in the Quick Snapshot and the sections above; health and memoir entries are tied to the same Rolling Stone coverage cited in the snapshot.
The pattern: the timeline has no gap longer than five years — every downturn in Mustaine’s story comes with a release date attached.
What’s confirmed, and what’s still unclear
With a story this long, the hardest task is separating the documented record from the folklore. Here’s the split, as sourced above.
Confirmed
- Metallica fired Mustaine in 1983. (Wikipedia (community encyclopedia))
- He was diagnosed with stage 1 throat cancer in 2019. (Rolling Stone (music magazine))
- He has been in remission since 2020. (Rolling Stone (music magazine))
- His memoir In My Darkest Hour was published in 2025. (Rolling Stone (music magazine))
What’s unclear
- Exact net worth as of 2025 financial filings — estimates range from $14 million to $20 million. (Celebrity Net Worth (celebrity finance tracker))
- The precise current relationship between Mustaine and James Hetfield.
- How much Dupuytren’s contracture will limit future performances. (Czech Wikipedia (community encyclopedia))
- Full details of Megadeth’s final album cycle and farewell tour dates.
The balance of evidence: the core biography is stable. The money, the friendship, and the hand condition are where the record goes soft — and those are exactly the details most likely to move before the farewell tour ends.
Dave Mustaine in his own words
A few quotes capture the contradictions — the provocateur, the survivor, and the band’s designated closer.
“Thank God that genre went away.”
— Dave Mustaine on nu metal, as quoted by Blabbermouth (metal news site)
“A final chapter.”
— Dave Mustaine on Megadeth’s farewell album and tour, as reported by LouderSound (metal magazine)
“The next album will be the band’s last, and a farewell tour will follow in 2026.”
— Megadeth, August 2025 press release, as summarized by Wikipedia (community encyclopedia)
For fans, Megadeth’s 2026 farewell tour is the last live window into a catalog that started as revenge and aged into canon. For Mustaine, every remaining date is proof that the 1983 firing and the 2019 diagnosis both failed to stop the story. For anyone who grew up on Rust in Peace, the choice is simple: buy the ticket while the farewell is still a tour, because after the final show, the only versions of these songs anywhere near you will be played by someone else.
