As the music blasts out, a sea of frenzied women chant “take it off” as the chiselled guy on stage prepares to whip off his final item of clothing – a Union flag.
The screaming 1,500-strong crowd in the sold-out club is a heady mix of hen parties, booze and fancy dress and the atmosphere is hysterical.
But for the Dreamboys – Britain’s answer to the Chippendales – this is just a normal Saturday night.
There is not a greasy barnet or G-string in sight and with their boyband good looks and choreographed dance routines, they are like One Direction… but with a lot more muscle.
I am in a £149 ringside seat around the dance floor, surrounded by giant inflatable willies the audience have brought along with them.
A group of 20 hens are dressed as sailors and raring to go.
The not-so-blushing bride Sarah Young, 31, tells me she wants “to see their penises or I’ll ask for my money back”.
In fact, during the show only one man actually goes the Full Monty.
Tonight, it is Tyson Brown, a 31-year-old former account executive with the rather telling nickname, the Aubergine.
But there is a whole show to get through before that, and after some lewd banter from Sophie, the warm-up drag queen, it begins.
Bursting on stage dressed as firemen there’s not a muscle in sight and it is more like a Diversity dance routine than anything else.
But soon enough the tops come off and the girls go crazy.
The boys work their magic, straddling gob-smacked hens. Some grab the chance to touch the boys’ rippling six packs.
When one of the Dreamboys comes over to me and sits on my lap I don’t know where to look, I haven’t had nearly enough to drink, unlike most of the women around me.
With the boys finally down to their briefs they suddenly stop , scoop up all their clothes and run off the stage to a chorus of angry boos.
For the next hour there are more dance routines to chart tracks and cheesier numbers such as I need a Hero, with the boys dressed as pilots.
But the most the girls get is the odd bum flash, revealing the tiniest muscly buttocks I have ever seen. Without a willy in sight, the ladies are baying for more than just dance moves.
