The 'Will & Grace' Cast Sang Lyrics To The Theme Song & They'll Make You Laugh

Much to the delight of fans across the globe, Will & Grace is returning to NBC for a brand new season. Not only that, but the revival has also been given the green light for a second season, which seems to suggest that the reboot is going to be all kinds of epic. While promoting the the upcoming season premier of Will & Grace on The Tonight Show Starring Jimmy Fallon on Friday, Sept. 22, the cast performed the Will & Grace theme song, but with brand-new lyrics. Actors Debra Messing, Eric McCormack, Sean Hayes, and Megan Mullally were also joined by host Jimmy Fallon during their hilarious performance that will get you even more excited about the revival — if that's at all possible.

Oh and in case you didn't get the memo, the entire original series is currently available to stream on Hulu, as of Thursday, Sept. 21. That's right, you can watch all 194 episodes of Will & Grace ahead of the reboot's premier on Thursday, Sept. 28. Or, if you've already been catching up during weekend Will & Grace binge-a-tons on the WE TV network (*raises hand*), then you can catch up on episodes that haven't aired on television recently.

With the season premier almost upon us, the Will & Grace cast has been out promoting the reboot in full force. They've been doing tons of interviews, and are super active on social media, but their Tonight Show performance totally takes the cake.

"I'm Debra Messing as you probably know," Messing announced as she kicked off the performance set to the Will & Grace theme song.

"You might remember me from the cast of the show

Grace is a character that I play

She's an interior designer and Will's roommate

"It's more fun than you could ever know," Mullally (who played the iconic Karen Walker) sings after she later joins the rest of the cast on the show, likely joking about the fact that the original show's season finale was basically forgotten in the reboot. Mullally went on to sing, "only show on NBC not set in Chicago," definitely joking at the fact that the network has a number of shows that are set in the Windy City.

Check out the amazing video of Messing, McCormack, Hayes, Megan, and Fallon singing and dancing to the Will & Grace theme song below, and seriously, prepare to smile!

The cast also sat down for a group interview with Fallon, where they shared a few interesting stories from production on the original show. For example, did you know that Hayes initially had been considered for the role of Will, which McCormack went on to portray. And Mullally apparently had auditioned for the role of Grace before she was invited back to audition again, but for the role of Karen.

As Fallon points out, the group really do seem like they could be friends in real life. Judge for yourself by watching the video of their interview.

The first season of the Will & Grace report will be 10 episodes, which is certainly a shorter season than us fans of the original Will & Grace are used to. But NBC ordered at least 13 episodes of the next season, which is a sign that the network has faith in the reboot. And why shouldn't they? The previews for the show look great, and us fans of Will & Grace are practically chomping at the bit for the show to premier.

McCormack perfectly capture the excitement among fans during the cast's performance on The Tonight Show when he sang, "Get down, Will & Grace is coming to town!" With that being said, feel free to let your Hulu binge watching session begin.
