The project arose when, at the same time MGM engaged Hemmings for an album, the Byrds recorded the song Don't Make Waves for the soundtrack of the MGM film of the same name. Early Byrds co-manager Jim Dickson was enlisted to be the producer of Happens, with the group's guitarist, Roger McGuinn, and bassist, Chris Hillman, playing on the record as session musicians. McGuinn and Hillman also contributed the music to a couple of songs over which Hemmings rambled improvised lyrics. Too, the album included a song by ex-Byrd Gene Clark, Back Street Mirror, that was never recorded by Clark or anyone else. Without time for rehearsals, the LP was cut in a mere week or so.
Although Hemmings had been a boy soprano with the English Opera Group, by the time Happens was done in his mid-twenties, his voice had a rusty, strained, and unimpressive timbre. Happens ended up as a mediocre period novelty-relic that alternated between dainty orchestrated folk-rock and contrived, semi-improvised raga rock. The album sold virtually nothing when it was released in September 1967, and had not been reissued at the time of Hemmings' death in late 2003. ~ Richie Unterberger, Rovi
