Will Ferrell Decides Coldplay Performance Needs More Cowbell

When a song needs more cowbell, Will Ferrell is there to deliver. At "Will Ferrell's Best Night of Your Life" Saturday, a charity event produced by Funny or Die to raise money for cancer survivors, Chris Martin was performing an acoustic version of Coldplay's "Viva La Vida" when he got some unexpected backing instrumentation, Time reports. Namely, Ferrell, who crashed the performance with his cowbell in a nod to one of his most famous Saturday Night Live sketches. See the video in our gallery. In other Martin news, despite recent rumors, he's apparently not expecting a baby with Dakota Johnson. (More Will Ferrell stories.)
