Sister Act The Musical arrives in Liverpool this month and to celebrate the Empire theatre has 20 nuns visiting the city on Saturday 12 May from 1pm to 5pm, and simply by getting a card stamped, the public can win tickets to see the show.

The 20 nuns will be shopping, dining, visiting attractions, having coffee and appearing in unexpected places in Liverpool One and Albert Dock. The theatre has four sets of four tickets to give away in a prize draw. All people have to do is get hold of a stamp collection card from either Liverpool One Info centre, Albert Dock Tourist Information Centre in Anchor Courtyard, Radio City Tower reception or from the Radio City crew who’ll be around the town handing out cards. Then search out the five groups of nuns, get your card stamped and when you have all five stamps, hand it back in to be in with a chance of seeing the musical at the Liverpool Empire with three friends.

This first ever UK and Ireland tour of the musical comedy, produced by Whoopi Goldberg and Stage Entertainment, arrives at Liverpool Empire on Tuesday 22 May and runs until Saturday 2 June.

Sister Act The Musical stars Liverpool-born actor Michael Starke, who is best known for his role as Thomas "Sinbad" Sweeney in Brookside, which he played for 16 years. The cast also includes Coronation Street’s Denise Black as Mother Superior, and Cynthia Erivo as Deloris Van Cartier.

Completed cards can be handed in at Liverpool One Info centre, Albert Dock Tourist Information Centre, Radio City Tower reception or posted to: Sister Act Nun Day, Liverpool Empire, Lime Street, L1 1JE.

Entries must be received by 5pm on Thursday 17 May.
