Invited guests of MINE are always welcome on stage, but the customer who volunteers himself or another patron rarely gets the nod from me. I get paid to entertain, not to babysit, and even though a spirited version of "what I like about you" just MIGHT get this guy into some girls pants .... it's neither my place or my wish to participate in the ritual.

As for someone playing my breaks - never on my gear. Sometimes a room has 2 acts booked. That's different. I've shared sets before, but I won't play "Ted Mack" to the amatures any more. When the norm becomes sing-a-longs and sit-ins .... that's when I start laying bricks.(in a matter of speaking)
