WATCH: BalletX gets the city dancing with 'Happy'

It’s been months since Pharrell Williams dropped his infectious tune, "Happy," and yet the hit continues to inspire smile-filled dance videos all over the world. In preparation for their summer series, BalletX made their own energetic "Happy" video.

BalletX, founded in 2005, is Philadelphia’s premier contemporary ballet company. Their upcoming summer series runs from July 9 until July 13 and will be a ballet about Captain Edwin Musick, the first pilot to take the treacherous flight across the Pacific Ocean in the 1930s.

The company dancers let their hair down for this video and enlisted the help of Philadelphians around the city, including some pretty impressive break dancing little kids in LOVE Park. This local ‘Happy’ video is far from the first. Camden’s Goodness Project and Temple University are just a couple of the other local ‘Happy’ dance videos floating around the net.
