I'm a long-time pianist/keyboard guy who's recently taken up the trumpet partly because I've always been ENVIOUS of the ability to flee the venue with only a small case under my arm. I play the penny whistle for the ultimate in escape-ability.
As the leader of a community-based big band I've had to have some serious, guilt-inducing "sermonettes" about
:
1. Please help tear down and put away ALL the band's gear.
2. If you can't carry, at least don't stand in the way while the rhythm section is trying to get drums/amps/bass fiddles/pianos off the stage and into the cars or storage rooms.
It's worked, though. My band does a great job of this.
BTW, the worst "band noodlers" by FAR are guitar players. The whole band will finally quiet down for a moment of instruction and the guitarist will just keep at it. Look him in the eye, remain perfectly still, and after a few minutes he'll say, "What??" They don't even know they're doing it. Those left hands have a life of their own, I guess.
