Stumbled across this debate. Yes - I'm guilty - I wrote it. All I can really reember is the chorus and it was written around that old joke that was mentioned. I had someone at The George & Dragon Folk Club in Sunderland translate the chorus into Russian and I used to do that for the last chorus - so there is the story of Geordie Broon. Twice recently I've had to request words of songs that I've written from hearing someone singing them. Most recently it was from my friend Jim Bainbridge. He's singing a song called "It's Nee Bliddy Good Gettin' Aahd[old]". It was a more north east earthy version of my Oldest Swinger Song. Fascinating this songwriting lark isn't it?
