Veteran Canadian comic David Tsonos hates one thing: the drunk heckler.

Once the sun goes down they come out, and since he can't beat them, he is inviting them.

The audience are issued paddles and raise them when they wish to heckle, which makes for a controlled-chaos atmosphere.

Watch David compere with three different guests as they take on the hecklers.

Tonight's guest acts are three of Bath's best up-and-coming comedians - Sam Hawkins, Holly Leggett and Ollie Young.

Some comics say it is their favourite show to perform on.
