The Turtles

The Turtles are best known for their 1967 hit "Happy Together," which went to #1 in America, knocking "Penny Lane" out of the top spot. Other hits include "You Showed Me" and "Elenore."

The killer app for The Turtles is the harmony vocals by group leaders Howard Kaylan and Mark Volman. They also sang for T. Rex, backing the band on their albums The Slider, T. Rex, and Electric.

Originally a surf band, they started out as the Nightriders and became the Crossfires in 1963. Kaylan was the leader and Volman was originally a roadie, but quickly became full-fledged member and Kaylan's primary collaborator. They became The Turtles in 1965.
