Shows extend: Jersey Boys, Viva Forever! & Les Miserables
The musical, which originally opened on Broadway in 2006, follows four boys on their journey from the wrong side of the tracks in the state of New Jersey to international success as pop music sensation The Four Seasons.
New cast members are due to start next week. From 12 March, Edd Post and David McGranaghan will join the London cast as Bob Gaudio and Nick Massi respectively. Ryan Molloy - who has been with the West End production since it opened in 2008 - will continue as Frankie Valli and Jon Boydon as Tommy DeVito, with Jon Lee playing the role of Frankie Valli at certain performances.
As part of the celebrations for the show's fifth birthday (on 26 March), the producers have launched Senior Sundays, whereby senior citizens are now able to see Jersey Boys for £27.50 at Sunday performances.
