Our first look at Allison Williams singing in NBC’s upcoming Peter Pan Live! has been released.

And her pipes aren’t bad!

The new 30-second spot also includes Christopher Walken in the role of Captain Hook, but he doesn’t sing in this promotional video.

Williams, in the titular role of Peter Pan, gives us a brief glimpse into her performance of “I Won’t Grow Up” with the Lost Boys. Check it out below:

In related news, check out this second recent promotional video which shows the amount of work that’s going in to Peter Pan Live! It’s so interesting how all of this work is being spent on a single live performance – it’s almost a shame that they can’t do additional performances for an audience in a theater!

Peter Pan Live airs Thursday, December 4 on NBC.
