I know how you feel Alan.
we have one Jack### who would come up every 5 mins and bug us about when am i up and why does he have to wait so long. and that is when we have a rotion of 25 or 30 singers. but he thinks he is the best out there and people want to hear him over the others.
So everytime he comes up i told him i would drop him down two in the list. and i did.
he dosnt bother us anymore. Bob
