'Will & Grace' Stars Perform Show's Theme Tune With Lyrics For First Time

If you’ve ever wondered what the lyrics to the “Will & Grace” theme song may sound like, this video could answer some of your questions. Kind of.

The NBC sitcom’s stars teased the show’s upcoming revival by joining “Tonight Show” host Jimmy Fallon on Friday to sing along to the catchy tune.

And according to Fallon, it’s the first time it’s ever happened.

See Debra Messing, Megan Mullally, Eric McCormack and Sean Hayes belting out the number, with a little help from Fallon, in the clip above.

The revival premieres at 9 p.m. ET on Thursday, Sept. 28 on NBC.
