An unusual comedy act came to Norwich last night, and if you are afraid of the dark then it was definitely not for you.

The Comedy in the Dark show came to Cinema City as part of its UK tour, bringing an unusual twist to stand-up comedy.

Screen one of Cinema City was plunged into darkness, total darkness, so dark that you couldn't see the person next to you.

As a narrator introducing the gig over the cinema's PA system had said at the start of the night, isn't it just like listening to comedy on the radio?

Well, no, as it turns out.

What the darkness brought into play was the secret weapon of many successful stand-up gigs, heckling from the crowd for the comedians to use as material.

With the lights turned down, the packed-out audience were more than happy to get involved.

The host for the night was Birmingham comedian David Morgan, who kept the crowd entertained in between sets from Radio One DJ Tom Deacon, blind Liverpudlian Chris McCausland and Ireland's Keith Farnan.

Openly-gay Morgan provided a fun running joke from early on when he took a fancy to a teenage couple in the front row, in particular a chap called James.

Fortunately James was up for a laugh and ended up taking to the stage so that Morgan could show the rest of the audience what he looked like.

I suspected that the show was going to be quite repetitive, with constant jokes making use of people not being able to see the comedian, but it wasn't.

Deacon got a good laugh when the lights were turned back off after he came to the stage, by grabbing someone in the front row's leg to see what reaction he got. Unfortunately for Deacon, just like the majority of his set, the reaction was disappointing but still got a laugh.

The real masterstroke was blind McCausland though, who remained dead-pan as he told the crowd they knew just how every gig was for him now that they had seen comedy in the dark.

Farnan finished the night on a high by poking some fun at his home country of Ireland, but it was the crowd who were the real stars.

Amid the darkness people were able to contribute to the comedy throughout the night with heckles that they may not have been as confident to shout out with the lights on.
