The Coldplay frontman has performed the unreleased piano ballad 'Wedding Bells' for Apple.
He played the song for Apple: the elite computer company, not Apple: his strangely-named daughter.
Martin introduced the song as 'Wedding Bells' and suggested that it may never be released.
It's not the first time that he's aired the song.
Rolling Stone notes that he played a version on acoustic guitar on British television, saying then "It's actually better on guitar, I think."
Coldplay are currently in the middle of recording their follow-up to Viva La Vida with Brian Eno.
They've previously previewed new tracks 'Christmas Lights' and 'Don Quixote/Spanish Rain'.
Of course, someone videoed the 'Wedding Bells' performance, so have a listen below.
