Watching The X Factor musical I Can't Sing has been compared to taking LSD.
The elaborate new West End show – penned by comics Harry Hill and Steve Brown with the blessing of X Factor boss Simon Cowell – stars Cynthia Erivo and Alan Morrissey as Chenice and Max, two lovestruck singers who decide to enter the talent contest.
But before they can achieve stardom, they have to win over the judging panel, comprising fictional versions of Simon Cowell (former EastEnders actor Nigel Harman) and Louis Walsh (Ashley Knight), as well as Cheryl Cole parody ‘Jordy’ (Victoria Elliott).
The show also stars a dog, of course, called Barlow, voiced by Avenue Q's Simon Lipkin.
And speaking to us last week, Simon gave some insight into just what the show was like.
"I don't know if I'm allowed to say this but Harry Hill was walking out of the theatre the other night and he was walking behind this older couple who said, 'I've never taken LSD, but I imagine that's what it's a bit like'.
"It's unlike anything, this show more than any other really embraces that kind of sketch show craziness and the style of the music is amazing. "
Well there you go.
Unfortunately for the show's crew, some of Harry Hill's ideas have been a bit too far out there to actually make it into the show.
"It's fun, bonkers, Python-esque, Harry Hill-esque, it's just a great night out. If you embrace it you'll enjoy it," Simon said. "Some of the things in Harry Hill's brain that he wrote down on paper are just not physically possible, it's like 'How do you achieve that!?'"
