First recorded (as “What a Man”) by Linda Lyndell (R&B #50 1968).
Other hit version by Salt N Pepa (US #3/R&B #3/UK #7 1993/AUS #2 1993).
From the wiki: “Linda Lyndell sang in gospel churches as a child; though she was white, she sang in both white and black churches, and eventually began singing with R&B groups as a teenager. In the 1960s she sang as a support act with James Brown and Ike & Tina Turner, and in 1967 Atlanta disc jockey Dave Crawford tipped her to Stax Records producers Isaac Hayes and David Porter. They recorded her first single, ‘Bring Your Love Back to Me’, in December 1967 and released it on Volt Records, but the song did not become a hit. In 1968 she did a second session, cutting the tune ‘What a Man’. The song was essentially improvised in the studio by Lyndell, record producer Dave Crawford, and the Stax studio musicians in Memphis, TN.
