In the early and mid-1960s, Bacharach wrote well over a hundred songs with David. In 1961 Bacharach discovered singer Dionne Warwick while she was a session accompanist. That year the two, along with Dionne's sister Dee Dee Warwick, released a single "Move It on the Backbeat" under the name Burt and the Backbeats. The lyrics for this Bacharach composition were provided by Hal David's brother Mack David. Dionne made her professional recording debut the following year with her first hit, "Don't Make Me Over".
