Hi Earl, thanks for the transcription. I couldn't make out that line you queried either - at first, it sounded to me a bit like 'old mayor so-and-so', but that's not it. The recording I have is from a 1956 Riverside recording and has some differences with the version you transcribed. For instance:

He's on the rock pile now
He's on the rock pile now
I told Bill to go head home
And leave those white folks business alone
Bill's on the chewing gum now

Definitely sounds like 'chewing gum' or else he's saying 'chain gang' in a very strange accent. Are you sure about 'apeyard' in the last line? If so, do you know its derivation? Sounded like 'eight yard' to me, but that makes no sense.
