Story goes Larry David the creator of the sublime Seinfeld and Curb your Enthusiasm was once a stand up comic. He would walk out infront of an audience and if he didn't feel the warmth from the crowd he would just say “Naa.” and walk off! No explanation . Nothing. I often say in our little concerts to the audience “This is a 2 way street”. My brother played in the AFL and he told me that “you would not believe the difference a home crowd makes.” I always found that astonishing in something like football. Elite athletes play better when people are cheering for them. I think its really really important that when parents see the shows they take an active role in the other 50 percent- the whooping and yelling and the laughing. It makes a massive difference. You see the kids rise to the occasion when the wind is behind their sails.
