The song "I Ain't Gonna Marry" which Maria Muldaur has been singing for at least 50 years -- what is the source for that tune? Maria and Jim Kweskin say it was learned from a 78 of a female singer. So, not the Alabama Sheiks, and not Brantley & Williams' "Cat's Got the Measles, Dog's Got the Whooping Cough" (their version is killer!!). It's not Ida Cox's Lawdy Blues. Anyone know??
