The song “ The Happy Organ” originally featured lyrics and was intended to be
sung accompanied by a piano and an organ. Cortez recorded a vocal for it but
was unhappy with the result. He spotted a Hammond B3 organ in the studio and
decided to play the song’s melody on it. He also brought in legendary studio
drummer, Gary Hammond, to provide percussion. The guitar solo is by session
musician Wild Jimmy Spruill.
