Hmm, the folk process or braincell decline?! I remember it as "developing transverse thrust in me epicyclic overdrive torque condenser unit." Who'll check their vinyl first!

Ref "Swinger" authorship and credit given: When I interviewed Fred for Southern Rag in 1982, he said about it:

"Swinger I picked up by pure chance - I did a little club up near Milton Keynes, stayed with the club organiser and the next morning he played me some tapes of Iain MacIntosh. He was singing this version of Swinger - the tune was pretty duff and to be honest quite a few of the words were as well. But I thought there was great potential so I scribbled it down . . . Without being uncharitable to Ed Pickford, the lines which have been quoted most were the ones that I wrote in. Quite a lot of the song. The first verse is all Ed's, and several of the other ideas . . . he'll make a lot more money out of it than me, I should think £20,000 at a conservative estimate."

Which tallies with what Chris Newman said above.
