Tensions within the band finally erupted in August 1967, during recording sessions for "The Notorious Byrd Brothers" album, when Michael Clarke quit the group over disputes with his bandmates and his dissatisfaction with the material that the songwriting members of the band were providing. Session drummers Jim Gordon and Hal Blaine were brought in to replace Clarke temporarily in the studio, although he continued to honor his live concert commitments with the group. Then, in September, Crosby refused to participate in the recording of the Goffin–King song "Goin' Back", considering it to be inferior to his own "Triad", a controversial song about a ménage à trois that was in direct competition with "Goin' Back" for a place on the album. Crosby felt that the band should rely on self-penned material for their albums, rather than cover songs by other artists and writers. He would eventually give "Triad" to the San Francisco band Jefferson Airplane, who included a recording of it on their 1968 album, "Crown of Creation".
