jim gordon was the most prolific studio drummer in the mid to late sixties into the late seventies. if you listen to classic rock and oldies stations, you're hearing jim all the time. they say he went over the edge when he was in dereck and the dominos, as he and clapton became addicted to speedballs. the heavy drug use excaserbated his paranoid schizophrenia and as the seventies wore on he started hearing voices, particuarly that of his mother, and he wound up on her doorstep with a hammer and bludgeoned her to death. he made a fortune as he wrote the piano piece to "layla", and still receives royalties. he is periodically up for parole.
