 The track was written by Sherman Marshall and Phillip T. Pugh, and produced by Thom Bell.Released during a time that Warwick's chart fortunes were at an ebb after moving to Warner Bros. Records in 1972, the Philadelphia soul single was a rare mid-1970s success for the singer.Sung as a duet with Spinners main lead singer Bobby Smith and the Spinners, who were one of the most popular groups of the decade, the song became Warwick's first ever single to reach number one on the US "Billboard" Hot 100 and also became her highest-charting R&B record reaching number two on that chart, behind Barry White's "Can't Get Enough of Your Love, Babe" (itself a Hot 100 number-one single).
