AN EDINBURGH FRINGE musical conceived in a Mexican internet café, performed in a portacabin off George Square and starring a young professional actor who started out with Tryst is transferring next month to London’s West End.

Over the Threshold was conceived by writer/composer Christopher Hamilton and has captured five-star reviews since it opened on August 6.

It stars Kieran Brown (we know him as Barry Brown) who performed with Tryst in the 1990s in such shows as The Secret Diary of Adrian Mole and Under Milk Wood.

After its run ends at George 2 Musical Theatre on August 31, Over the Threshold opens in London’s Jermyn Street Theatre – famed for showcasing new musical theatre - on September 21 and will run through to October 4.

The London shows could mean a big career breakthrough for Kieran (30) who plays Tom, an out-of-work actor.

He said: I’m proud to be part of Over the Threshold and thrilled that we’re moving to London.

“I love doing new musical theatre. It’s important to support new writing and I also love the challenge of creating a new part from get-go.”

Kieran is a former member of Falkirk Children’s Theatre, Falkirk Youth Theatre and Tryst. Since graduating from Glasgow's Royal Scottish Academy of Music and Drama, he has taken part in a number of European musical tours and now spends much of his time in Vienna.

Added Kieran: "There's only a piano accompanying us and it's a very simple but effective set. I know I can't really be objective since I'm involved in the show but the music is to die for."
