In June 1966, Davis left to play with Bobby Kris & The Imperials and Lillie learned to play bass in two weeks to fill the spot. Around this time, an American duo with the same name appeared on the charts and the group was forced to adopt a new name, The Group Therapy, for its show at the Varsity Arena on June 22, supporting The Byrds. When another local group surfaced with an earlier claim to The Group Therapy name, Merryweather came up with the new name, The Tripp, in September 1966.
