I never thought I would say it, but maybe John Kirkpatrick is right about playing tunes that stand alone- over and over ,trying to get different ways of playing. I certainly would like the opportunity to "jam" with some tunes, riffing and trying out counter melodies. I think it's pretty difficult with irish stuff, but English hornpipes can be tackled. It gets a bit indulgent, and customers in the pub would probably get fed up, but there you are!
