Will Ferrell has made a guest appearance during Chris Martin’s charity set on Saturday night, playing cowbell alongside the Coldplay frontman.

If you ever had to educate someone on the topic of musical comedy, the iconic ‘More Cowbell’ sketch from Saturday Night Live will inevitably come up. One of Will Ferrell’s finest moments, he’s since brought out the cowbell on numerous occasions since, including with Queens Of The Stone Age, the Beastie Boys, and even alongside Red Hot Chili Peppers drummer Chad Smith.

Now, the comedian has teamed up with Coldplay’s Chris Martin for his latest performance.

As Rolling Stone notes, Chris Martin was a musical guest at Los Angeles’ Greek Theatre on Saturday night for the ‘Best Night Of Your Life’ cancer benefit.

Performing a two-song set, Martin was halfway through a rendition of his 2008 track ‘Viva La Vida’ when Will Ferrell took to the stage.

With Chris Martin unable to control his laughter at times, Will Ferrell played the cowbell with such finesse that Martin soon challenged him to an impromptu guitar vs. cowbell battle that ended as quickly as it began.

However, this wasn’t the only memorable performance of the night, with Chris Martin being joined by a number of huge musical stars for his last song of the night, a cover of Pink Floyd’s ‘Comfortably Numb’.

With the evening’s band consisting of Duff McKagen (Guns N’ Roses), Mick McCready (Pearl Jam), Chad Smith & Josh Klinghoffer (Red Hot Chili Peppers), Stefan Lessard (Dave Matthews Band), and Brad Paisley, Chris Martin was in good company as he ripped through a performance of the 1979 classic.

While the rest of the evening featured a number of comedians and entertainers keeping the crowd going, Will Ferrell was a constant presence throughout the night, reviving his Ron Burgandy character, twerking as Donald Trump, and even posing as Brad Paisley’s fictional brother Gary. Needless to say, it seems like quite an event.
