One reason why a lot of young instrumentalists prefer sessions to clubs is that at a session they can play all night,but at a club they now usually only get a two song spot,then have to listen to boring old farts like me,and they have to pay for the priviledge.At least one club I attend on a regular basis has a pretty fair fiddler who usually leads a tune session in the interval,and also encourages musicans in the audience to join in when he does a floor spot.Not a bad scheme,i feel.
