[1] The group recruited drummer Billy Mundi and bass guitar player Jim Fielder for live performances, opening for The Byrds and Buffalo Springfield during spring 1966.

When Mastin left during sessions for an album, Brewer enlisted his brother Keith and the pair recorded a lone single 45 for Columbia Records, "Need You", backed by "Rainbow" (written by Tom Mastin and Brewer before the former's departure).

After recording the single, Brewer met his old friend Tom Shipley and they initiated a duo together.

Their third album, 1970's Tarkio, included the song "One Toke Over the Line," which became an unlikely pop hit in 1971, reaching #10 on the Hot 100.

[1] During 1983, Brewer released an LP, Beauty Lies, of which Dan Fogelberg was the producer.
