Ocean's first single, "Put Your Hand in the Hand" (from the album of the same name) sold over one million copies in 1971 in both America and the band's native Canada. The gospel-rock band was comprised of Greg Brown (vocals, keyboard), Jeff Jones (bass, vocals), guitarists Janice Brown and Dave Tamblyn, and drummer Chuck Slater. Several singles followed during the early '70s, but none were as popular as the debut. Ocean disbanded in 1975.
