While it's been a long long time since we've seen actor Will Ferrell play the cowbell, the Saturday Night Live sketch in which he did just that remains one of his most beloved.
This weekend saw Will doing "more cowbell" once again, with Coldplay frontman Chris Martin!
Saturday night was funnyman Ferrell's big charity event Best Night Of Your Life, and it was star studded! One of the performers was Chris Martin sans the band, though he did get some help. During the performance of Coldplay hit "Viva La Vida," Will took the opportunity to back Chris up playing none other than the cowbell.
