I read this story last night. I can't say I'd remember Whithall's name but I sure remember the Marvellettes. They, along with many female groups from Detroit at the time, sure had that "Motown" sound that I fondly remember.
I remember very well, Mr. Postman and probably just as famous, Beachwood 45789. Sorry to hear of her passing.
