MASTERPIECE's production sans music of Les Misérables may be finished, but you can watch the entire series if you sign up for WGBH's Passport. As for the singing version, tonight we celebrate the legendary musical with a stellar cast including Alfie Boe, Nick Jonas, Lea Salonga, Colm Wilkinson, Norm Lewis and Ramin Karimloo. Staged by producer Cameron Mackintosh, the concert was filmed at London's O2 Arena.
