I've come a bit late to this discussion but I'll start with saying that anyone who disagrees with Mr Gill has me on his side automatically. If the unpleasantness of said Mr Gs comments were intended to see off the riff raff he certainly succeeded with me.

Having said that an unaccompanied tune played well is a thing of beauty and obviously stands up well as it is. No one will ever know if it could have been improved with another s playing once the moment has gone.

I'm a guitar player and about 15 years ago I spent about 6 months devising and learning to play an instrumental section in the middle of a Jimmy Rodgers song. 6 months! I finally felt up to trying it in a session and someone picked up a 12 string and joined in with the wrong chords. Hi Ho.
