It is also known by other names & one is" Marching Through Rochester" and it is on U tube sung by Jim Herd & Dick Holdstock on 2 separate u tube recordings. I think Pete Coe gets the credit for putting it to this tune as his name always appears in brackets.
Thanks Geoff. The merry folk at Gregson Lane folk club in Hoghton pointed me in the direction of their Facebook page, and you back up what they told me. Not sure if the Wassailers are still going in any capacity. Be nice to find out. I'm currently living in Essex, buying a house in Burnley and hoping to move back to Lancashire in a couple of months so I should be in a better position to make a few contacts then and do a bit of research.
Thanks again, pal.
