I once said (very knowledgably because I heard it on the Radio) that it was Wigan. The listener pointed-out that not only had Wigan station gone by then but he ran the folk club in Widnes and booked Paul Simon.

The Poet was either Roger McGough or Adrian Henry ( my failing memory) and the "One Man Band" was Don Partridge.

I was suitably humble after that - for about 5 minutes.
