"Fountain of Love" is a collaboration between Frank Zappa and soon-to-be Mothers of Invention singer Ray Collins. It dates back to the early '60s, when both were working with recording engineer/studio owner Paul Buff and trying to produce pop hit singles. It was first recorded in 1962, but this version remained unreleased until its inclusion on the 1996 rarities collection The Lost Episodes. It was dusted down and re-recorded in 1968 for the Mothers' doo wop pastiche album Cruising With Ruben & the Jets. In The Real Frank Zappa Book, the man described the lyrics as being "sub-Mongoloid," taking the doo wop norm to extremes. One can only agree when reading the first two lines: "It was September, the leaves were gold/That's when our hearts knew that story untold." The ballad features piano triplets, three-voice harmonies, the whole doo wop package. On the 1968 version, while the song fades out one can hear Roy Estrada singing the first six notes from Igor Stravinsky's "Rite of Spring" -- typical Zappa humor. There are no records of the song being performed live, which is not a loss.
