Considering the earlier stories about Led Zeppelin on this rumor list, mainly involving the mudfish incident, we can't say we share much sympathy for the fact that the night John Bonham died he ingested 40 shots of vodka. Whilst death by vodka may not be the most extreme collision a rock star has had with their mortality, it's really not surprising that 40 shots of vodka is enough to finish someone off.
After he passed away on September 25th, 1980 the coroner found 40 shots worth of vodka the day he died, which he had consumed following a rehearsal earlier that day. The official cause of death was determined as inhalation of vomit. Nice. At least the sex charges won't stand.
