The Rocky Horror Show is a musical theatre experience like no other. For a start, you dress up in the most outrageous and provocative or transsexual costume you can find, you’re expected to dance along to the Time Warp and you shout ‘slut’ or anything else that comes to mind when Janet comes on stage.

The story follows Brad and Janet, a young, naive couple who have just got engaged. After getting lost in the rain and their car breaking down they stumble upon Dr Frank-N-Furter’s castle of transvestite. He welcomes the couple into his home and lab, where he unveils his latest creation – a young, muscular man called Rocky. Both Brad and Janet get lost in the doctor’s weird world, while his associates namely Riff Raff and Magenta attempt to take over the castle and transport it back to their own planet.

The narrator Norman Pace was incredible – not just for his performance, but his witty comments to audience remarks and how he bounced off them and gave his own twist as he continued to narrate the show.

Liam Tamne had some big shoes to fill as Dr Frank-N-Furter and he did a brilliant job – he was eccentric, loud, had a stunning voice and was the stand-out performer.

Richard Meek made an incredibly convincing, geeky Brad and Diana Vickers certainly looked the part of a naive Janet. Her accent was impressive and although I liked her singing, my friends described it as irritating. Their duet in There’s a Light stood out for me, especially as the audience starting waving glow sticks or using the lights on their phones, which was a nice touch.

I was disappointed to learn that Dominic Andersen, who plays Rocky, was injured and his understudy, Will Knights had to take over. Will was ok, he had a decent voice but he did get the lyrics wrong in Rose Tint My World and lacked charisma.

Other than that the show was fantastic, full of energy right through to the end. Although the plot doesn’t make a great deal of sense, yYou are somehow drawn into the weird world of Dr Frank-N-Furter and can’t help but sing along and dance, and you leave with a buzz. Richard O’Brien’s musical is certainly a classic.
