Covering favourite shows like Into the Woods, Company, Follies and Sweeney Todd, as well as some lesser-known numbers, the concert will be presented by Olivier Award winner Sara Kestelman (Cabaret, Nine) and feature West End performers Jalisa Andrews (Nativity Rocks), Luke Bayer (Everybody's Talking About Jamie), Stephen John Davis (Phantom of the Opera), Will Haswell (Back to the Future), Rebecca Jardine (Gigi), Will Luckett (Saturday Night Fever), Carly Paoli (Classical Brit nominee), and Monique Young (Mary Poppins).

A professional six-piece band will accompany the concert, which will mark what would have been the week of Sondheim’s 93rd birthday.

The programme will include such favourites as ‘Tonight’ (West Side Story), ‘Putting it Together’ (Sunday in the Park with George) and ‘Comedy Tonight’ (A Funny Thing Happened on the Way to the Forum). Proceeds from the concert will go to the Actors’ Church Benevolent Fund.
