Mickey Finn was the
percussionist/
drummer with the
1970s Glam rock group
T. Rex (formerly known as Tyrannosaurus Rex).
Marc Bolan (
1947-
1977) asked Finn to join the band in the late
1960s and reportedly only hired Finn for his good looks and not for his
musical ability.
Mickey Finn is also a slang term for a drugged drink, given to someone without their knowledge in order to incapacitate the victim.
