With the comedy behemoth that is the Edinburgh Fringe kicking off, we’ve got a special preview show with four must-see comics at the Festival. We find out about Tony Law’s faulty wiring, Marlon Davis explains how his last Edinburgh show got him fired, Sara Pascoe reveals why ‘Sara Pascoe tits’ is her most popular Google search (highbrow stuff this, innit?) and presenter Ben goes head to head with ‘grumpy young man’ Josh Widdicombe. And watch out next week as the bi-curious Dave podcast goes bi-weekly at the Fringe.
