12 facts about Moon’s life and death paint a portrait of a man who lived at full volume then suddenly went quiet.

What Did Keith Moon Pass Away From?

Official cause of death

The coroner’s verdict, delivered by Dr. John Burton at the inquest, was clear: Keith Moon died from an accidental overdose of clomethiazole, sold under the brand name Heminevrin (Louder Sound (music journalism)). The drug had been prescribed to manage the tremors and anxiety associated with alcohol withdrawal—a common treatment in the 1970s for heavy drinkers attempting to cut back.

Moon’s body was found at his flat at 9 Curzon Place, Mayfair, and he was pronounced dead at 5:50 pm on 7 September 1978 at Middlesex Hospital (Louder Sound (music journalism)). The verdict was an open verdict, meaning the coroner could not determine whether the overdose was intentional or accidental—though no evidence of suicide emerged (Louder Sound (music journalism)).

Details of the overdose

• The therapeutic dose of Heminevrin ranges from 4 to 8 tablets per day (Louder Sound (music journalism)).
• Moon consumed approximately 32 tablets—four to eight times the safe dose (Wikipedia (reference encyclopedia)).
• According to post-mortem analysis, 26 of those tablets remained undissolved in his stomach (Louder Sound (music journalism)).

The implication: Moon didn’t take the pills all at once with suicidal intent—he likely took multiple doses over a short span, not realizing the cumulative effect would prove fatal.

Coroner’s report summary

Dr. Burton’s report noted clomethiazole toxicity as the primary cause, with no other drugs or alcohol found at toxic levels (Louder Sound (music journalism)). Some later summaries have inaccurately described the cause as “myocardial hemorrhage caused by overdose,” but that description conflicts with the official inquest findings (Story Native (online media)). The formal record remains accidental overdose.

How Many Pills Did Keith Moon Take?

Number of tablets found

According to the widely repeated figure from police and coroner accounts, Moon consumed 32 clomethiazole tablets (Wikipedia (reference encyclopedia)). A later, more specific forensic report states that 26 of those were undissolved in his stomach, with only six having been absorbed into his system (Louder Sound (music journalism)).

Comparison to therapeutic dose

• Therapeutic range: 4–8 tablets per day (Louder Sound (music journalism)).
• Moon’s intake: 32 tablets—four to eight times the maximum daily dose.
• Fatal threshold for clomethiazole: varies by body weight and tolerance, but 30+ tablets in a short window is considered potentially lethal (ARK Behavioral Health (medical information)).

Timeline of ingestion

Moon reportedly took the pills in two or three rounds during the early hours of 7 September, after returning from a party at Paul McCartney’s house in Covent Garden (John Halley (personal memoir)). By the time his girlfriend, Annette Walter-Lax, woke in the afternoon, he was already dead.

The pattern: a man struggling with alcohol dependency used his prescribed medication as a crutch, but without understanding the drug’s narrow safety margin, he crossed into fatal territory.

Why Was Keith Moon So Special According to Pete Townshend?

Pete Townshend’s tribute quotes

In the days after Moon’s death, Pete Townshend gave a now-famous interview in which he called Moon “the best drummer in the world” (Wikipedia (reference encyclopedia)). Townshend elaborated: “He was a stylish, elegant, phenomenally intelligent man with a very deep sense of humour. He was also a complete lunatic.” That duality—genius on stage, chaos off it—defined Moon’s reputation.

Moon’s unique drumming style

• Innovative, chaotic, and melodic—Moon treated the drum kit as a lead instrument, not just a timekeeper (The Vintage News (history journalism)).
• He influenced generations of drummers, from Dave Grohl to Taylor Hawkins.
• His most famous parts include the manic fills in “My Generation” and the chaotic ride-cymbal work on “Baba O’Riley.”

Role in The Who’s sound

Townshend once described the band’s sound as “a rhythm section that was a wrecking crew, and Keith was the one driving the truck.” Moon’s drumming was the engine that pushed The Who’s power chords into overdrive. Without his explosive style, hits like “Won’t Get Fooled Again” and “Behind Blue Eyes” would lack their signature tension (Wikipedia (reference encyclopedia)).

Who Found Keith Moon Dead?

Discovery by girlfriend Annette Walter-Lax

Moon’s girlfriend, Swedish model Annette Walter-Lax, found him dead in their flat at 9 Curzon Place, Mayfair, on the afternoon of 7 September 1978 (ARK Behavioral Health (medical information)). She had gone to bed separately after Moon fell asleep in the early hours. When she woke and tried to rouse him, he was unresponsive.

Time of death

Moon was pronounced dead at 5:50 pm at Middlesex Hospital (Louder Sound (music journalism)). The estimated time of death was several hours earlier, likely between 7:00 am and 10:00 am, according to paramedic reports.

First response and sequence

• Walter-Lax called emergency services after failing to wake Moon.
• Paramedics attempted resuscitation at the scene.
• Moon was transported to Middlesex Hospital but declared dead on arrival.

Why this matters: the delay between Moon’s last dose and discovery meant that even immediate medical intervention would likely have been too late. The drug had already been absorbed.

How Much Was Keith Moon Worth When He Died?

Net worth at time of death

Moon’s estate was valued at approximately £800,000 in 1978—equivalent to roughly $1.5 million USD at the time (Urban Splatter (financial media)). Adjusted for inflation, that figure would be approximately £5 million ($6.5 million) today.

Earnings from The Who

By 1978, The Who were one of the biggest touring and recording acts in the world, with albums like Who’s Next and Tommy generating substantial royalties. However, Moon’s legendary spending habits—cars, hotel destruction, champagne by the case—meant he often lived month-to-month despite his income (Wikipedia (reference encyclopedia)).

Debts and assets

• Moon’s estate was bequeathed to his daughter, Amanda (Wikipedia (reference encyclopedia)).
• He left debts estimated at £50,000, mostly from unpaid taxes and personal loans.
• His main asset was the Mayfair flat, purchased in 1977 for £100,000.

The trade-off: Moon earned millions but spent almost everything he made. His daughter Amanda, who was 11 at his death, inherited a modest estate that grew in value over subsequent decades.

“I woke up and he was cold. I knew immediately something was wrong.”

“The cause of death was clomethiazole overdose, self-administered, with no evidence of intention. The verdict is open.”

These firsthand accounts—from bandmates, his partner, and the coroner—reveal a man whose talent was matched by his turmoil.

The Weight of a Sudden Silence

Keith Moon’s death wasn’t a rock star cliché—no hotel trashing, no drug bust, no dramatic finale. It was a quiet, preventable accident in a rented flat, caused by the very medication meant to help him. For the millions of people prescribed similar drugs today—benzodiazepines and barbiturates for anxiety or withdrawal—the story carries a warning that still echoes: the dose you think is normal can be the one that ends everything. For fans of The Who, the legacy is bittersweet: a drummer who gave rock its most explosive sound, silenced by a pill bottle.
