Russell Brand, Johnny Vegas and Dara O'Briain appear in archive clips and interviews where they reveal the realities behind playing to a late night noisy audience.

In Programme 1 what makes the late night comedy club truly unique is introduced - the audience. For 25 years, for the month of August, during Edinburgh Fringe, Late'n'Live has opened its doors at 1am each night and presented 3 acts, a compere and a comedy band to a very scary audience.

Consisting of largely locals, this audience let the acts know exactly what they think of them and have raised heckling to an art form. Subsequently, it has earned the international reputation at the world's toughest gig - a bear-pit where even the strongest acts have died horrible comedy deaths.

Key contributors in Episode 1 are: Johnny Vegas, Jenny Eclair, Dara O'Briain, Russell Brand, Stephen K Amos, Ed Byrne and Mark Watson.
