I always sing it as per the Pomona Palace dance hall that was just off Albert Square at Pomona docks, now part of Salford Quays. Whether that is the origin or whether some words were just about near enough to make it about Pomona, I don't know, but that's how I introduce it.

Thinking on, I first heard The Two Beggarmen introduce it as that, although my first recollection of the song was the late Tom Brown used to sing it regularly at The Boundary in Worksop many years ago. (Old Tom possibly introduced it as first hearing it at his mother's knee, as per every song he did, bless him.)
