The gang is back as Will & Grace returns to fall schedule to lead NBC's revived Thursday night Must See TV. However, the biggest question is, what, if anything, has changed?

During Monday's upfront presentation at Radio City Music Hall, Eric McCormack, Debra Messing, Megan Mullally and Sean Hayes appeared in a teaser for the return of the successful NBC sitcom, which originally ran from 1998-2006. In the video, McCormack and Messing, playing versions of themselves, go from the NBC corporate offices back to the Will & Grace set to bring the show back but Messing is afraid. What if things have changed? Once they bump into (who else?) Karen (Mullally) and Jack (Hayes) in their old apartment, it seems that things haven't changed much. In fact, the scene turns into a musical number with the quartet of stars.

Check out the clip here and see if you think the gang still has what it takes to get us laughing this fall.
