All the excitement of the Broadway stage will be broadcast into viewers' homes this week, as Broadway Week has returned to LATE NIGHT WITH Jimmy Fallon (12:35 a.m. ET on NBC) featuring a new musical number each night. Last night, Fallon welcomed David Alan Grier and the cast of PORGY AND BESS, who performed 'It Ain't Necessarily So,' and you can check out the musical number below!

The supernatural power of love comes to studio 6B Wednesday, February 22 when the cast of "Ghost The Musical" stops by. Adapted from the Award winning film, the show follows the love story of Sam and Molly while Sam struggles as a ghost trapped between two worlds. The production officially opens this upcoming spring.

Thursday night's show will feature Roundabout Theatre Company's 2011 Tony Award winning musical "Anything Goes." Sutton Foster takes the "Late Night" stage to sing a rousing selection from this saucy production set on the S.S. American. The show was the recipient of three 2011 Tony Awards including Best Revival and Best Actress in a Musical (Foster).

The week concludes with the Whoopi Goldberg produced "Sister Act" on Friday, February 24. Based on the feature film which starred Goldberg, this musical comedy has received rave reviews for its feel-good energy and rocking dance numbers.

"Late Night with Jimmy Fallon" is produced by Universal Television and Broadway Video. Lorne Michaels is the executive producer. Michael Shoemaker produces. Gavin Purcell is the supervising producer.
