Given the fact that one of Farrell’s specialities was bubblegum pop (as music publisher, he also represented the writers of Paper Lace's "The Night Chicago Died" and the Cowsills' "Indian Lake"), it only followed that Columbia’s label subsidiary Bell Records would hire Farrell to be musical producer of The Partridge Family. Claver would have been content to lip-synch everything and use studio singers like Jackie Ward and John and Tom Bahler, who had shored up the vocals for the Brady Bunch and other singing TV stars in the 1960s and 1970s. But Cassidy, an amateur musician who also fancied himself a songwriter, wanted to try his hand at vocals, and auditioned for Farrell by singing along to a Crosby, Stills, and Nash record. Farrell was drawn to Cassidy's tremulous, feline croon, and agreed that he should sing lead on all of the tracks. Shirley Jones, for her part, had it written into her contract that she contribute background vocals on all the Partridge Family material. “Shirley did those oop-oops so she could get some extra money for those records,” says Claver.
