Thomas Scot Halpin, The Man That Filled In For Keith Moon Back In 1973, Dies

It was 1973 at the Cow Palace in San Francisco, California, and an inebriated Keith Moon had passed out. Pete Townshend asked if there was anyone in the audience who could play drums. Scot Halpin stepped up and filled in for Moon. He would go on to win Rolling Stone Magazine’s “Pick-up Player of the Year Award.” Halpin died on February 9 at 54. For more on the story, click here.

That's the only time that Moon was unable to perform at a concert, which is strange because his drinking really picked up around 1976-77, when The Who were not touring as much.

Keith Moon died in 1978 after attending a film preview with Paul and Linda McCartney of The Buddy Holly Story. He had overdosed on a drug intended to curb his drinking.
