Daniel Boys, most recently seen in the West End in Avenue Q and Wolfboy and soon to be seen in Ordinary Days, will host the event, which will also feature appearances by the companies of Jersey Boys and Priscilla Queen of the Desert, both singing songs from the show. Also, Mamma Mia!'s dance captain Tim Stanley will be joined by members of the company to teach the show's finale to the audience; the cast of Stomp will lead a workshop on body percussion; and Legally Blonde's resident director Dominic Shaw and the cast will give a unique "jump rope" demo.

In a press statement, the Mayor of London, Boris Johnson commented, "Hats off to the Society of London Theatre. As well as the packed onstage line-up, they've added an exciting programme of activities and events. Get Into London Theatre means you can bag a bargain at a time when people are watching their pennies and is a delightful fillip for the chilly first months of the year. It's a fabulous opportunity to discover why our theatre industry is the envy of the world."
