Incidentally, Bernard, I dispute that the reference is to Pomona Docks, which only date from c 1890 when the Ship Canal was completed (sorry, I havent got the precise date to hand).There was a Pomona lock on the earlier Bridgwater Canal, but I think you will find that the Pomona of the song refers to the area pre-Dock, when there was a Pomona pub and the whole area was a sort of pleasure gardens/Irwell side shrubbery//place of ill-repute sort of thing, in the mid-1800's. Just the sort of place, in fact, where you would take a young lady you had just picked up in Albert Square, if seeking alcoholic refreshment, followed by somewhere alfresco for some discreet frolicking. And, of course, nothing whatsoever to do with Lamorna(though you can frolic there to your hearts content as well....I know this as a good old Cornish boy).
