On the day of an Old Firm clash, a Rangers and Celtic fan end up sharing a courtroom cell.

Their only hope of escape is betting on the match to pay their fines.

While taking turns to watch the game on a TV through their cell door, the pair bicker their way through every entrenched cliché of “Scotland’s shame” from religion to politics and national identity.

But aided by their kindly turnkey Harry – whose worries for his sick grandson help put their petty quarrels into perspective – they’re forced to reach a grudging understanding.

‘Singing I’m no a Billy, he’s a Tim’ by Des Dillon’, has been one of Scottish Theatres biggest success stories. A satire of bigotry in Scotland and its connection with the nation’s two biggest football teams first scored critical acclaim at the Fringe in 2005.

Singin’ I’m No A Billy He’s A Tim is on at Barrfields Theatre on Friday 2 October at 7.30pm.

Tickets are available from www.barrfields.com, from Vikingar or by calling 01475 689243.
