I do this song often. I think Woody left the ending a bit to the person's imagination on purpose, but it would seem that the lawyer never made it back to Philadelphia.
There was a PBS special about Woody in which Rose tells a bit about the song, but it was mostly about how she got it from Woody. It was a very big hit for her and her brothers, but she said that they made no money from it, except for the fame. I guess Woody was not the only one screwed by the record companies.
