I don't allow drinks in the singer's area either. I've had people spill them, forget them, and come back up to fetch their drinks while another singer is performing. Just a bad idea to allow them. But can't quite understand the logic of not allowing a singer's disc. Thats what i'm there for. I'm never too busy to accomodate a singer with their own disc. I have songs no one else in the world has, and i want to sing them. Could care less what's in the book. You would be doing me a diservice by not allowing me to sing them. JMHO...
P.S. Sound Choice is the exception. A sound choice product is noit allowed in my club. My rules. Management has no say so over my rules for karaoke. I don't serve drinks, they don't host karaoke. Been a winning combination.
