Tiffany Mason, self-titled greatest vocal tutor the world is ever going to meet, is here to teach you to sing. But just as she’s about to get you to ‘slap the disabled child within you’ who is only holding you back from that top E sharp, the sirens are heard and Mason must back out of the room with her hands in the air. What follows is a fast-paced narrative of Mason’s downfall told through a multitude of sketch characters, all played by a quick-changing Alison Thea-Skot and her near-mute sidekick.The show started on shaky ground with the somewhat clichéd character of the arrogant theatrical and an over-reliance on simple vulgarity for laughs. However, her ability to get a rather scant audience to partake in her music lesson was impressive and as she hauled the audience into her world and the narrative got going the show become increasingly enjoyable.There were a couple of standout characters Thea-Skot had mastered. The inappropriately cheery CBeebies presenter, who had accidentally found herself the sole reporter on a hostage situation, was original comedy genius, demonstrating to the audience a model of the crime scene we could all make at home with just some loo roll and a bit of sticky tape. A social worker explaining to us her fool-proof techniques in coaxing the truth out of a child witness whilst in obvious earshot of her bewildered subject was well-timed and full of unforeseen humour.Unfortunately Thea-Skot’s penultimate role as a badly-trained barrister fell short of the rest. It seemed a lot more could have been done with this sketch which she failed to get a hold of. Instead she made obvious, and annoyingly unrealistic, gags such as accidentally saying her client was guilty rather than innocent: ‘I get the two confused’.Despite the few shortcomings, there was no doubt that every audience member left the show with a smile spread wide across their faces. This fine comedian certainly knows how to get an audience sucked into her zany world of preposterous personalities and larger than life situations leaving the room on a high as she takes her final bow. Give Thea-Skot a go and she’ll have you laughing in perfect harmony.
