"Pomona is a song about The Pomona Palace, in Albert Square, near Pomona Docks, in Salford. (McColl could have sung an indigenous song there if he had thought on...)"

I think that this needs a bit of clarification. The Pomona Palace pub is just off Chester Road and is probably in Hulme, in Manchester, not Salford (Salford is to the west, across the Bridgewater and Manchester Ship canals). I say 'probably' because, on the ordnance survey map, the district is called 'St. Georges' and is close to the border with Stretford. Over the last 40 or 50 years the whole area has been extensively 'carpet bombed' by 'progress' - so, to an adopted Mancunian like me, the exact geography is not terribly clear (so much for clarification!). I don't know if there was ever an Albert Square around the area in question - the only Albert Square that I know is a mile or two away in the centre of Manchester.

Oh yes, Ewan MacColl may have been born in Salford but both of his parents were Scots and he learned several songs from them.
