Remember a few weeks ago when Katy Perry announced on GMA that she would be visiting one high school on her birthday for a very special performance in conjunction with the release of her new album, Prism? One high school created their own version of 'Roar,' and you've got to see this.

Lakewood High School Lip Dub 2013 - Roar from Lakewood High School on Vimeo.

The students and staff of Lakewood High School created a victory line winding through their school with lip-syncing to Katy Perry's 'Roar.' Utilizing students from every part of the school from the sports teams to the art club, the kids sing-a-long and create an incredible video set to the song.
