"Chris [Martin] once submitted a song to him with a note that said, 'Would you please sing on this song, because it's got this three-part thing,' and we had a sort of David Bowie–type character," the drummer recalled in a video for NME. "And Bowie came back, 'It's not a very good song, is it?' I was like, 'OK, I'll take that as a no.' So he was very discerning. He wouldn't just put his name to anything, so I'll give him credit for that."
Neither Champion nor guitarist Jonny Buckland, who appeared in the video with him, revealed what song they had submitted to Bowie or whether or not it was ever released.
Since Bowie's death last week, a number of musicians from a variety of genres have paid their respects. Yoko Ono, Madonna, his guitarist Carlos Alomar, Iggy Pop, Alice Cooper, Lorde, Chris Cornell and Ozzy Osbourne are all among the many artists who have written tributes.
