I suggest that whether a performer is good enough should be decided by an audition by a panel of four people, two men ,one of whom is capable of reducing potential performers to a quivering wreck by vicious put-downs, the other slightly more gentle , but still capable of being cutting where necessary.

There should be two females on the panel, one of whom should preferably be married to a famous footballer, and one who should be capable of being reduced to blubbering on behalf of the rejected performers.

Spice to the proceedings would be added by the judges continually arguing among themselves.
