Just fifteen days after first starting their comedy training, the five celebrities will take to the stage for one last gig. With the audience voting for their winner using the time-tested clapometer, who will have the last laugh and get top billing as the Stand Up And Deliver champion?

With just 24 hours to go before their big gig, our five brave celebrities are doing some last-minute comedy cramming in support of Stand Up To Cancer. Judi Love coaches Curtis in improvisation, Nick Helm teaches Sayeeda how to make a strong first impression, and Jason Manford is still struggling to get his protégé Shaun to remember his act.

Meanwhile, Katie McGlynn attempts to harness her nerves and Reverend Richard Coles remains reverent when David tries to push on him a joke with two swear words in the same sentence. He's keen to win the competition, but not at the expense of his day job.

There are nerves all round as the gig day finally arrives. Faced with stepping on stage all alone in front of 300 people, both in person and virtually projected round the entire venue, the reality hits home for our five famous faces. Even confident frontman Shaun loses his nerve, and Jason is forced to rush to the rescue of his comedy apprentice.
