Tweet yourself to free ticket for hit show

Twitter users are being offered free tickets to see a comedy musical in the West End after the producers praised online word-of-mouth for making the show a hit.

Betwixt! is to get an extended run at Trafalgar Studios until September 10 after playing to packed audiences.

Producer Christopher D Clegg said: "Many of our fans have been back two, three or even four times." Betwixt! tells the story of New York writer Bailey Howard and his roommate Cooper Fitzgerald, who are plunged into a enchanted world.

The "Be-Tweet" performance is on Monday. To get a free ticket Twitter users must tweet why they deserve one on the site.

Mr Clegg said: "You then have to post a picture/video/audio file/blog/vlog/drawing that sums up why you love Betwixt!"
