Kids love a good old icky story or nauseating image, don't they? Well, their appetite for the grotesque will be sated by two appearances from Jay Foreman at the Glasgow Comedy Festival as he brings us a series of 'disgusting songs'. But does he know where the line is for him not to cross? 'One of the most fun things about performing for kids is that it's impossible to out-gross them,' confirms Foreman who has been doing musical comedy for both big people and smaller ones since around 2005. 'There's a lot of audience interaction in my show, so when they shout out suggestions I learn a lot about how horribly disgusting kids' minds are. I think it's more accurate to say that my show is too disgusting for grown-ups.'

Once dubbed as 'Victoria Wood for the Spotify generation', Foreman's repertoire of tummy-upsetting tunes includes 'Caterpillar Sick', 'I Fell into a Sewer', and 'A Man Covered in Jam'. So what makes his own flesh crawl? 'My sister once came up with the most gruesome thought I'd ever heard of: a sofa upholstered in living human skin, which sweats and scabs and flakes and stinks and all the other things human skin does. Naturally I decided it should be turned into a song, and I'm pleased to say "Skin Sofa" always goes down an absolute treat in the show. At least it does with the kids, they laugh their heads off, but I've seen grown-ups properly wincing during that song, which I think means I'm doing my job right.'

The Stand, Glasgow, Sat 28 & Sun 29 Mar.
