The line-up for 2023 Cambridge Theatre show in London was Matt ParkerHelen Arney, Yuriko Kotani, Mithuna Yoganathan, Yolanda Ohene, Lucy Cooke, Dan Schreiber, Grant Sanderson of 3Blue1Brown, Ayliean MacDonald, Count Binface, and a specially created 5-part vocal ensemble: Molly O’Gorman and the Firebrands.

Again, we really cannot recommend enough that you join our mailing list to hear about everything we are up to, as soon as it is announced… there’s so many things coming up in and out of London, we don’t want you to miss out on any of it.


Stand-up mathematician Matt Parker, experiments maestro Steve Mould and geek songstress Helen Arney each talk about something you might not believe could be interesting, but turns out to be utterly fascinating when you get down to the nitty and / or gritty. Also featuring new songs from Helen!
