John Gary Driscoll (18 April 1946 - 8 June 1987) was an American R&B style rock drummer who performed in a number of successful bands from the 1960s until his death on June 10, 1987.
He first entered the music scene when he joined Ronnie Dio and The Prophets in June 1965, fronted by Ronnie James Dio. The band transformed into The Electric Elves, The Elves, and finally Elf in 1969, releasing a few singles along the way. They were eventually discovered by Deep Purple bassist Roger Glover who went on to produce two of Elf's three studio albums.
Elf disbanded in 1975 when Gary Driscoll, Ronnie James Dio,Micky Lee Soule (Elf's keyboardist), and Craig Gruber (their bassist) were recruited by Deep Purple guitarist Ritchie Blackmore to form the rock band Rainbow.
Driscoll was dismissed from Rainbow shortly after their debut album, entitled Ritchie Blackmore's Rainbow, was recorded. It is speculated that firing Gary was simply due to his R&B style of drumming, which did not sit well with Blackmore. Driscoll was later replaced with British hard rocker, Cozy Powell.
