Maria Muldaur is the voice on the "answer" part of the song - who's the male singer? The earliest version of this song I can find is the Memphis Minnie version that Jim posted above. Foghat did an interesting version, too - the one I like best is by Jim Kweskin
CHEVROLET (version by Jim Kweskin Jug Band)
Well, I'll buy you a Chevrolet, I'm gonna buy you a Chevrolet, I'm gonna buy you a Chevrolet, If you'll do somethin' for me. If you'll do somethin' for me.
I don't want a Chevrolet, I don't want a Chevrolet, I don't want a yellow Chevrolet, And you can't do nothin' for me. Oh, no, you can't do nothin' for me.
Well, I'll buy you a diamond ring, I'm gonna buy you a diamond ring, I'm gonna buy you a diamond ring, If you'll do somethin' for me. If you'll do somethin' for me.
I don't want your diamond ring, I don't want your diamond ring, I don't want your diamond ring, And you can't do nothin' for me. Oh, no, you can't do nothin' for me.
Well, I'll buy you a cutting board(?), I'm gonna buy you a cutting board, I'm gonna buy you a cutting board, If you'll do somethin' for me. If you'll do somethin' for me.
