Keith Moon. Died September 6, 1978.

Keith Moon was an infamous pillhead his entire career as The Who's charismatic drummer. At one point he was keeping a fishbowl of assorted uppers and downers at his bedside. When Moon tried to kick his habits he died of an overdose of the sedative Clomethiazole, which was supposed to help alleviate his alcohol withdrawal symptoms. But Clomethiazole is intended only for supervised detox due to its addictiveness, tendency to rapidly induce tolerance, and dangerously high risk of death when mixed with alcohol. Keith had 32 pills in his system. Six were sufficient to kill him.
