Notable productions after World War II include Stop the World I Want to Get Off in 1961, A Suite in Three Keys in 1966, and Wonderful Town in 1986. In 1996, Stephen Sondheim's musical Passion ran for 232 performances and in 1999 Maggie Smith starred in The Lady in the Van. The most notable production at the theatre is Les Misérables, which moved there in 2004 and celebrated its 14,000th performance in 2019.
