Wow -- always great to see another Baby Washington fan. Talk about under-rated (or even unknown.) Let me know if you like Bertha Tillman too!
Bertha Tillman was certainly under-rated. Although "Oh, My Angel," her biggest hit, only made it to #61 on the Billboard Hot Hundred in the spring of '62, it was for years a popular "oldie" in LA. If you have the original 45, it should be worth some bucks.
Another great baby Washington opus is "Lonely Nights" by The Hearts, a "doo wop" tune in which she sings lead, from 1955.
