The Turtles

Though they hit number one in 1967 with the infectious "Happy Together," the Turtles scored only three more Top Ten hits and broke up by the end of the '60s. Kaylan and Volman later joined Frank Zappa's Mothers of Invention throughout the early '70s and additionally recorded themselves as Flo & Eddie, but were on the oldies circuit with a revamped Turtles by the mid-'80s.
