DtG: You know the line 'effum' if they can't take a joke. IF people don't invite you back, then you have tabooed yourself out the door. However, I have it on very good authority that you'd have been more than welcome in Bob Copper's club. He felt it an obligation, duty and honour to keep his family's songs alive, but he was never precious about other people doing their music in his club.

When you're with other musicians, and if they give you a 'look' then back off a bit. Keep in mind that good sessions involve as much listening as playing, maybe even more. Gi'e it a try and see. And best wishes to you that it's successful and fun.
