Marilyn Haywood was a background vocalist on albums by Eddie Harris, Bo Diddley, and Ahmad Jamal. Her song Mama's Baby (Ain't A Baby No More)  is a girl power groover of the first order, with a hot laidback slapping groove and an amazing lead vocal from the under appreciated Haywood. Marilyn’s release came out on the Silver Fox label in 1970. The song was later covered by the Attractions (Girl group) in the mid 70s and saw some dance floor action as a favourite Mecca sound. In my opinion Haywood’s version is far superior and can be picked up for £5-£10. If you can't find the single you will find it on the 'Action speaks louder than words' CD, which also includes an alternate take on Sam Dees 'Lonely for you baby'.
