From the wiki: “‘Just One Look’ was written by Doris Troy and Gregory Carroll. Troy, then going by her pen name Doris Payne, recorded a studio demo of the song and began to shop the song around to studios, first to Sue Records. But their lack of response led Troy to instead offer the song to Jerry Wexler at Atlantic Records. Unbeknownst to Troy, Atlantic would later release her demo, unchanged, as a single.
