Morrison's character Will Schuester, according to the Hollywood Reporter, will perform "Still Got Tonight," which was penned by "American Idol" winner Kris Allen, Andrew Frampton and Steve Kipner.

The scene, which was directed by Ryan Murphy, features Morrison on stage in an empty theatre.

"It was going to be just a big dance piece with me doing this big dance number," Morrison told the industry paper. "But they said, 'We want you to sing it and make it a big moment.'"

Songs on the new CD also include "Summer Rain," "Let Your Soul Be Your Pilot," "My Name," "Hey," "Somewhere over the Rainbow," "Don't Stop Dancing," "It Don't Matter to the Sun," "Mona Lisas and Mad Hatters/Rocket Man," "It's Over" and "Arms of a Woman."

Morrison will begin a 20-city U.S. concert tour this summer, launching June 18 at the Orpheum Theatre in Minneapolis. Morrison received a Tony nomination for his work in Light in the Piazza and also appeared on Broadway in South Pacific, Hairspray, A Naked Girl on the Appian Way, The Rocky Horror Show and Footloose. On "Glee," he plays high school show-choir director and Spanish teacher Will Schuester.
