Lovelles
This girl group came from Tampa, FL and it’s members were Zulema Rucker, Brenda Hilliard and Albert Bailey. Their initial recording was for Charles Fuller who leased the Supremes sound-alike sides to Brent. By 1968 they were regular houseguests at Atlanta’s famous Pink Pussy Cat club where they met producer Dave Crawford. He took the trio down to Muscle Shoals to record a session with Roy Lee Johnson. Johnson and Crawford wrote and produced both sides of their excellent Atco 45. 
Pretending Dear just shades it for me thanks to a rather better melody. But I’m Comin’ Today also has that first class Fame sound as well as a typically stinging slide guitar solo from Duane Allman.
The trio moved to New York in the late 60s where they met Sam & Dave and joined their revue for a couple of years touring all over the world under the name Faith Hope and Charity. Back in the Big Apple in the early 70s they joined up with producer Van McCoy who started off their impressive run of hits.
