T. Swift + Broadway Stars = Awesome New Video

Around here, we can’t get enough of Taylor Swift’s “Shake It Off” video. And as if we needed another reason to keep the song on repeat, the Broadway cast of Mamma Mia! just gave us one.

Not only are the Mamma Mia! triple-threats super-hilarious, the video gives us an exclusive backstage tour of the show’s Broadway theater. We’re taken through the stage door into the dressing rooms, quick-change areas, the orchestra pit—and even a rehearsal space where some of the show’s dancers work it for a fabulous dance break! Check it out below—the goofiness will totally make your day!
