Hi Murray,
Yes, I'm aware of that one, but all I'm saying is in the particular version that I have he sings Fandance and not Fanlight. It's even printed on the track listing as Fandance Fanny. Perhaps it's a copyright thing? I don't know, words change I guess, as do the arrangements. I would imagine though Fanlight to be the original lyric, but why it was changed for that recording is anyone's guess... I guess!
Cheers,
Trev
