I am absolutely sure this was originally a Mancunian song...but the more nationalist Lamorna fans do point out there is an Albert Square in nearby Penzance! But seriously, the song makes no sense at all in a Lamorna context, anmd every possible sense in thew context of a Mancunian lad taking a lady of easy virtue down to the Pomona pleasure gardens by the Irwell in a carriage.
And words and sheet music exist for the Manchester version, I have been told, but I can't find them.
