Personally, I think the two extra verses don't match up to the original. Whilst the Macnaghten "I'm not a butcher" wasn't ever likely to win any prizes, at least it scans passably well. In comparison "Up and down the goddamn town" is appallingly bad, and seems to have been written by a poet of much lesser skill... which is saying something.
