Frankly I think we have to be grateful some people shun the limelight. There is nothing more off-putting in a session that the musician who thinks he's wonderful, knows more tunes than anyone else and can't wait to show off his absolutely deafening instrument so he can be louder than everyone else as well! But more seriously, of course privacy should be respected but one often encourages a good musician because their excellent playing gives us all so much pleasure.
