Coldplay’s Chris Martin was joined onstage by a cowbell-toting Will Ferrell at the comic actor’s all-star cancer benefit Best Night of Your Life. The event, which took place Saturday at Los Angeles’ Greek Theatre, featured a solo acoustic performance of Coldplay’s 2008 single “Viva La Vida.”

During Martin’s set, Ferrell emerged onstage, cowbell in hand – a nod to the legendary Saturday Night Live sketch – as the singer performed. Martin visibly tried to stifle his own laughter as Ferrell pranced around the stage, with the two soon treating the audience to an acoustic guitar-cowbell showdown.
