HiDO NOT be intimerdated!! 'THAT' fiddler is probably just interested in having a session as much as you. He never got to the level he was to make you put your fiddle down!! Take the chance of such a good player passing by, get some tips of him and improve yourself with his visit. You obiously respect him and the best way to show your respect to this good player is to play not put it down. Now pick up your fiddle and play, its what you enjoy!!
Cheers, Sam
