Jamie Raven admitted something could go wrong during his live magic show last night - and it did.

Sadly for the talented magician, there was a hiccup as he took to the stage at Watford Colosseum during his first UK theatre tour.

After he invited a male guest on stage to get involved with one of his tricks, he wowed the audience by bringing out stocks and a massive chainsaw.

He told the audience he would be able to run the chainsaw over the man’s head while it was in the stocks.

But at that moment disaster struck.

With hundreds of people sitting in the audience, the chainsaw got stuck and the man was unable to remove his head from the stocks.

Raven – who shot to fame during the 2015 series of Britain’s Got Talent - told the audience to “talk among themselves” as help came and the man’s head was freed – laughing as he took his seat.

He was asked to help during a later trick and happily obliged. It seems the mishap didn't spoil the show, with many taking to social media to thank the magician.

Jamie is currently touring the UK.

Watford Observer:

Our verdict:

Jamie Raven is a born performer. That much has been clear since he appeared on last year’s Britain’s Got Talent.

Charming, funny and always engaging with the crowd, Raven delivered a set of classic, familiar tricks but each had a twist at the end to convince even the most cynical of audience members. 

Some tricks worked better than others. Some of the card tricks felt less inclusive than the bigger spectacles. But it was when he drew in the audience with more spectacular illusions that he excelled.

Take the large-scale trick he performed halfway through the act. At odds of over 27 trillion, Raven somehow managed to make five people appear exactly where he needed them to, whilst simultaneously getting them to select colours and ordering themselves at random.

Where Raven really came into his own was engaging with the audience. He built up a good rapport with young people that served him well and while he may have lost BGT to a three-legged dog, this tour could easily form the foundation to a successful career on stage.
