This show is supposed to hinge on two Sarah Louise Youngs: Sarah-Louise Young (with a hyphen), a little known actress and newish comedian, and Sarah Louise Young (without a hyphen), the highly successful and wealthy star of pornographic films and magazines who retired in 1997 at the age of 26 and is now training to be a lawyer in Germany.

So, you would expect the little-known actress to have done detailed research on her namesake pornography star from which the writing and the comedy of the piece would emanate.

Sadly, the delving for facts appears to have ended at a cursory reading of Sarah Louise’s CV on the internet which must have taken all of ten minutes. There is no evidence from the show that there has been any real attempt to get beneath the skin of the pornography star and her extraordinary life.

The show is in effect no more than a front for a cabaret performance of Sarah-Louise’s good cabaret singing voice.

There is no doubt the audience enjoyed some of her songs, but why was Sarah-Louise pretending to be paralysed? And why was she wearing a red PVC nurse’s outfit and fishnet stockings. It all went unexplained.

Unfortunately Sarah-Louise the actress is not much of a comedian and neither is her sidekick Michael Roulston. Her timing is poor and her material even worse. And when she started whining on about existentialism, you felt it was time for her to shut up shop and go home.

It was a great shame. This baffling and terrible production did not do justice to a good idea. Instead, Sarah-Louise the actress seemed to be looking down her nose her more successful and richer namesake who she constantly referred to as “Porno Sarah”.

If she had taken the trouble to track and meet her nemesis, as any half-decent journalist would have done, she would have realised Sarah Louise was the one controlling her own destiny in an unpretentious and lucrative career trying to make pornography beautiful.
