10. Keith Moon
The Who had been off the road for two years when director Jeff Stein brought them into London's Shepperton Studios to record live versions of "Won't Get Fooled Again" and "Baba O'Riley" for his documentary The Kids Are Alright. Stein was unhappy with their take of "Won't Get Fooled Again" and coaxed them back to the stage to play it one last time. That take wound up in his movie, and was the last time that Moon played with The Who. He died four months later in the same London apartment where Cass Elliott had died four years earlier.
