'Harry Potter and the Cursed Child'? Pfft. Forget the official, West End Potter saga. After a couple of experimental nights at the Camden Comedy Club, this (unofficial – we repeat: unofficial) Harry Potter comedy gig goes all-out for Hallowe'en, with a big, one-off show at the Leicester Square Theatre in the West End.

It's part-play, part strange piss-take from the consistently inventive Weirdos Comedy Collective, written by Weirdos head honcho Adam Larter and directed by Matthew Highton. Larter also plays Potter alongside a cast of misfits, including Mat Tedford as Ron, Marny Godden at Hermione and Joz Norris as Draco Malfoy, plus Cassie Atkinson (Professor McGonagall), Eleanor Morton (Ginny), Jon Brittain (Hagrid), Gareth Morinan and Laurence Owen. We predict at least three 'wand' jokes.
