“Stick to our chords”: Chris Martin rags Jacob Collier for his reharmonisation antics as they duet on a simultaneously stripped-down and more complex version of Coldplay’s Fix You

Jacob Collier’s reharmonised piano covers have become a staple of his live shows - in fact, he released a whole album of them back in 2022 - but when Chris Martin made a surprise appearance on Collier’s rework of Fix You at a recent show at London’s O2 Arena, the Coldplay frontman cheekily suggested that he should rein it in a bit.

Seated at a Rhodes piano, the first verse and chorus are all Jacob, but already, he’s jazzing things up a bit. And then the big reveal: up steps Martin from the front of the stage.
