Thanks for the help on the missing bits and I'm glad the posting will help Tangledwood. I guess in a pinch, I can make up something to fill the gaps, or wait til my Les Barker book arrives.
Regarding Leeneia's comments, I'm sorry she takes this seriously. Since taking up the ukulele, I've been the butt of many a joke and I accept it all with good humour.
In my experience, banjo players are the first ones to tell banjo jokes, accordion players love to pass along accordion jokes, etc.
There is no instrument that I hate or can't listen to (okay, maybe the musical saw...).
I think Les Barker's humour is universal. I'm not from the UK and I love his stuff. :-)
As for the idea that the song ridicules folk musicians because they are not commercial, I can't imagine anything further from the truth.
In the broadest sense, the song shows us folk musicians how "outsiders" might sometimes see us. We have no clue as to who the song narrator is, whether she is even a music lover, maybe she has no taste in music at all. Maybe the players down at The Sun on Fridays are actually not bad, but the narrator is a non-folkie who just wants some quiet down at the pub to have a pint.
It never hurts us to get a different point of view and see ourselves as someone else might see us, especially when it's done with humour. Pricks our little bubbles a bit!
