I suppose that more people can learn to tune an instrument than can learn to sing....and when the band is playing for a dance, tunes are great...but 'most' tune sessions are for the musicians, to learn, share (read *show off*) and do the trance thing...I can be impressed for a bit, but not entertained for very long.

I did watch 20 minutes of a 'fiddle down' late one night behind a barn...tween Mark O'Connor and Jimmy Giles... they both drank beer and played every wild lick they could dredge up...now THAT was entertaining!
