Cabaret has a tendency to be a little... risque, shall we say? It's probably something to do with its history as part of a Mediterranean brothel (although whether that's really the root is debatable), but it has nonetheless become an art form where to titillate can be as important as to entertain. That, plus being a welcome home to types slightly more on the "deviant" scale than, say, a UKIP MP, has just reinforced cabaret's reputation as the slightly racier cousin to more straight-laced theatre.

In EastEnd Cabaret's case, that has been taken to heart, as evidenced by their catalogue of, frankly, rather filthy songs. Diva-in-charge Bernadette Byrne oozes sexuality as she slinks around the audience in her skin-tight cat suit, looking for prey to sit on and croon at, while man/woman Victor/Victoria is ensconced behind her keyboard/sound desk but adds the aural dexterity that makes their music a whole lot better than classic cabaret stylings.

You can argue about their selling point(s), but you can't argue about the musical quality – this is really Victor/Victoria's show, adding vocal harmonies and a whole range of loop/keyboard effects (plus some rather enthusiastic playing). Without her, Byrne would be one of many – another cabaret crooner with plenty of confidence and enthusiasm, but not a lot of musical talent.

Victor/Victoria's intriguing get-up is also, I'm sure, part of their appeal: half man, half woman, quite literally down the middle, it's undeniable that he/she speaks to the cross-dressing, sexuality and gender-bending sides of cabaret.

But behind all of that, there's really not much to EastEnd Cabaret: the songs and music are clever, the characterisations of Byrne and Victor/Victoria fun, but this is basically just a gig: any show that may have existed is largely window-dressing, and it's the moments when they try and create some semblance of plot (the ridiculously long build up to "Rohypnol") when the show grinds to a halt.

Also, the endless stream of songs about sex gets old if you're more mature than a teenager – it's amusing at the time, but they're not songs you'll be humming on the way home, nor ones you'll recount to your friends with glee. They're very talented, undeniably so in the case of Victor/Victoria, and they've got a very good image, but EastEnd Cabaret need to do more to make their show more variable – and a little plot might help too.
