STAGE TUBE: Matthew Morrison and *NSYNC's JC Chasez Perform 'This I Promise You!'

Matthew Morrison created the role of Fabrizio in the musical The Light in the Piazza, for which he was nominated for a Tony Award. He returned to Broadway in the Lincoln Center revival of South Pacific in 2008. His other Broadway credits include A Naked Girl on the Appian Way, Hairspray, The Rocky Horror Show and Footloose.

Morrison can also be seen on GLEE, the genre-defying new musical comedy series. The show follows an optimistic teacher and a malicious cheerleading coach attempts to save McKinley High's Glee Club from obscurity while helping a group of aspiring underdogs realize their true star potential. GLEE is broadcast on Wednesday nights at 9pm on FOX beginning this fall. Currently, he's touring in promotion of his solo album. While in London, Morrison brought out a special guest to perform *NSYNC's 'This I Promise You' - original band member JC Chasez. Check out the performance below!
