Doris Troy. Gregory Carroll wrote "Just One Look" with Doris. She used her pen name, Doris Payne, as the author. She was born Doris Higginson in the Bronx. She began working as an usherette at the Apollo Theater using the name Doris Payne where she came to the attention of James Brown. Doris changed her stage name to Troy and started singing professionally with acts such as Solomon Burke, Dionne Warwick and The Drifters before she released "Just One Look" as a single on Atlantic Records. Although the British Invasion cut her US chart career short, she ended up doing backing vocals for such artists as The Rolling Stones, Humble Pie, George Harrison, Carly Simon, Dusty Springfield and more. She also did tracks for Pink Floyd on "Dark Side of the Moon" (1973.) I hope this is what you need. There was a lot of listings on this song, but this is the only one without the Hollies mentioned.
