I have frequented folk clubs and pubs from Norwich and North Norfolk to Southend and North London. Yarmouth Town was and still is sung in almost all the East Anglian clubs and pubs, and has been since the early 60's, As very little info is forth coming I think this could well be a song discovered and edited by Pete Bellamy. Its origin could be almost any new world country that has a town named after the original Yarmouths of Norfolk and the Isle of White. Like many songs before it could have travelled back and forward across the Alantic over the years. With reference the the name of ' The Strand ' included in the song, I think this must be just be a familiar rhyming place name that rhymes with ' hand '. As far as I know that Great Yarmouth in Norfolk has no such road.
