Watch Kelli O'Hara & Matthew Morrison's Sizzling 'Tonight' Duet

The success of Glee pretty much guarantees we won’t be seeing Matthew Morrison on Broadway anytime soon, but the popular star gave us a taste of what we’ve been missing when he joined Kelli O'Hara to sing “Tonight” during A Capitol Fourth, the annual fourth of July special on the Washington DC mall. O'Hara introduced her pal and former stage co-star (South Pacific, The Light in the Piazza), who began his set with “Still Got Tonight,” a single from his new self-titled pop album. Morrison then adjusted his vocals to a more classical sound to match O’Hara’s peerless soprano on their West Side Story love duet. Click on and enjoy—and keep watching till the end for host Jimmy Smits’ amusing riff on WSS’s Bernardo!
