One of my favourite songs of my repertoirere. I tend to research my songs to death, on the basis that if the audience don't like my stuff they can at least go home saying "well, i learnt something new" I originally thought PG was a scottish song, till I started delving. I now introduce it as "An Irish version, of an English version, of a scottish version, of an American version, of a Canadian song from Nova Scotia. And the earliest version indeed has it's roots there in the 1950's. I'm sure it has influences in Scottish music. The late Luke Kelly first heard it in a Wolverhampton in 1967 and took it to Ireland where it's often regarded as Trad Irish. And I believe it was The Late Pete Seeger who first brought it to England in the early 60's
