The show, which is choreographed by WhatsOnStage Award-winner Andrew Wright and supported by the City of London Philharmonic Orchestra, will play a matinee and evening performance.

Celebrating composer Stephen Sondheim's 85th birthday year, the concert will feature the show's songs including "Losing My Mind" and "Broadway Baby".

Set in a crumbling old Broadway theatre scheduled for demolition, Follies sees two couples, Buddy and Sally Durant Plummer and Ben and Phyllis Rogers Stone, look back over their relationships during a reunion.
