I suspect Ian got this from the MacColl record. I had a whole rake of Folkways stuff bought from Rare Records in Manchester in the early 60's which I took to Hull with me when I moved there about 1965. Ian certainly listened to them.

Never knew about his son thoughand that is good news. There were times when I suspect he wasn't the best of fathers. Beryl his wife had a lot to put up with.
