At a fundraising concert for Chords 2 Cure (a pediatric cancer research foundation) in Santa Monica, California, Chris Martin surprised a delighted crowd by joining a rock band of 8th graders called A-Side and playing "Fix You," "Twisted Logic," and covering Prince's "Raspberry Beret" – what a magical, incredible thing to do for everyone, especially the young musicians on the stage (who played really well!)
