The boys of The Vamps are using their music for the greater good. And as if we didn't love their rework of Simon & Garfunkel's "Cecilia" already, Brad, Tristian, Connor and James gathered the talent of YouTube together to re-record the hit. After all, the guys found each other on YouTube, why not get everyone in on the Vamps goodness?

All proceeds from the song (sold on iTunes, but unfortunately not in the U.S. yet) go to Teenage Cancer Trust, a charity focused on helping young people get treated properly.

The video stars Tyler Oakley, Sam Pepper, Joe Sugg, Jim Chapman, Alexa Losey, Ebony Day, Benjamin Cook, Caspar Lee, Doug Armstrong, Patty Walters, Harrison Webb, Mazzi Maz, Sam King, Jake Boys, Chip Daddy, BriBry, Luke Cutforth, NikiNSammy, and Laura Bubble. Did you catch them all?

Tell us what you think of the rendition in the comments! (Also, tell us what you think of their "Pizza" rendition of "Cecilia.")
