YORK company Procter Goblins are trimming the premiere of their new promenade show, Grimm Up North, at Bar Farm Antiques, Barmby Moor, to Saturday and Sunday "due to unforeseen circumstances beyond our control". Tonight and Monday's 7pm performances will not take place.

The show will be staged around the farmyard and in the showrooms at Greg and Belinda Huber's farm buildings on the York Road going out towards Pocklington, about ten miles out of York.

Company co-directors Ben Rosenfield and Kirsty Wolff will play Kitty Echo and Mr Scratch respectively, part of Mr Scratch's Travelling Troupe of Grimm's storytellers. "They are broken, grotesque characters who've been travelling the world for so long," says Kirsty. "The idea is that they could do these Grimm tales anywhere; they've travelled to South Africa, Italy, Spain, Amsterdam, France...Bognor Regis, and now they've arrived on the A1079 near Pocklington."

Procter Goblins will be telling the tales of the Brothers Grimm "as they were intended" and with a Yorkshire twist applied. "It will be the most grim, gruesome, grotesque, sinister, outrageous, northern, just-about family show of the year, right on the edge, but no more so than a Roald Dahl story or even a pantomime – and it will be quite panto-esque," says Ben.

Alongside Ben and Kirsty will be Gavin Brooks, Emma Walker, Jimmy Johnson and Procter Goblins' regular squeezebox player, Ben Crosthwaite. "The show is a mash of old stories and modern music in a punk/folk/Klezmer style," says Ben. "Some stories are well known, like Hansel & Gretel; some are not so well known, like The Boy Who Went Out To Discover What Fear Was."

Tickets for Saturday and Sunday's 7pm performances cost £9.50, concessions £7.50, on 07772 523116 or at seetickets.com. Audience members should wear suitable clothing and are welcome to bring picnics and fold-up chairs; parking is available on site. A piano bar will be in operation.
