• A childhood ride in Elton John's Rolls Royce Phantom V that thrilled the young Damon Albarn inspired the song. Albarn recalled to Mojo magazine: "When I was about 7 or 8 - and this initially sounds very weird - I got picked up from school in Elton John's pink Phantom by his percussionist Ray Cooper, who was a friend of my parents. I was going to his nephew's party, who was my friend. It was very, very, very exciting."

I just slipped in the idea that we should do a Gorillaz thing with him."
