Actress Barbara Parkins, who starred in the motion picture, suggested that Warwick be considered to sing the film's theme song.
A recording by Warwick appeared on the B-side of her (original) single of Burt Bacharach and Hal David's "I Say a Little Prayer", a big hit which peaked at no.
In April 1968, the RIAA-certified gold Scepter LP that contained the hit version of the song, Dionne Warwick in Valley of the Dolls, peaked at no.
Charlie Blaum states "“Valley” had all the ingredients of a huge hit: a great singer at the top of her game, a gorgeous melody, an inviting arrangement, and most of all the haunting, soulful lyric by Dory Previn — look her up.
2, where in February and March it remained for four weeks, stuck behind two blockbuster singles: Paul Mauriat's "Love Is Blue" and Otis Redding's "(Sittin' On) The Dock of the Bay".
