Michelle McManus (pictured), the winner of TV’s Pop Idol in 2003, will star in a new Nativity-inspired musical comedy called Discotivity, which premieres at next month’s Edinburgh Fringe before transferring later this year to the West End’s Arts Theatre, where it will have a limited Christmas season from 4 December 2007 to 30 January 2008.

Discotivity is billed as “a unique version of the Biblical Nativity story revisited and revitalised as an unseasonal panto romp set to the pump of the disco beat”. Use it up and wear it out while Mary and Joseph and their mouthy donkey Tiffany Turner boogie on down the dusty road to a stable in a Bethlehem full to bursting. Thrill as the shepherds leave their flock and go off in search of the new King. Shake your body down as the Three Kings journey to the Messiah bearing gifts that would even turn Posh Spice's head. As for Herod, he's well bad.

Since winning Pop Idol in 2003, McManus, who hails from Glasgow, became the first Scottish female to debut at Number 1 with her single “All This Time”, which was nominated for an Ivor Novello Award and has been presenting on Scottish radio and television. She has previously appeared on stage in The Vagina Monologues. No further casting has yet been announced.

Commenting on her role as Mary, mother of God, McManus said: "People may be surprised that I've chosen to play this role, but I loved the script. And I've always wanted to perform at the Edinburgh Fringe. Also, as an aspiring actress, I felt this was a great challenge and would be a lot of fun as well!"

Discotivity is written by former DJ and music journalist Toby Rose, with a Seventies musical soundscape by DJs Luke Hope and Alan X. The premiere production is directed by Russell Labey, with lighting by Mike Robertson and choreography by Tara Wilkinson. It’s produced by Kevin Wilson (The Lisbon Traviata).
