P.P. (aka) Pat Arnold was originally one of The Ikettes, Ike and Tina Turner's backing girl group. She left Los Angeles and emigrated to England and signed to Immediate Records in 1967, and had a huge hit with "The First Cut Is The Deepest". Another single on the same label, "Everything's Gonna Be Alright", which was basically just a re-write of Bobby Scott's soul classic "We're Doing Fine", (also covered by Dee Dee Warwick)
