The jazz singer, who is married to TV chef Sophie Dahl, said he wrote Wheels, which is released next month, with the help of one of his friend’s children.
Jamie Cullum was musically inspired by a four-year-old
He said the song uses the “notes and construction” that a four-year-old showed him on the piano.
Jamie said: “I was driving along one day in January 2009 when the credit crunch was just starting to bite and the weather was terrible.
“This line came to me ‘The wheels are falling off the world’. I wrote it down and didn’t really do anything with it. Then a friend brought his four-year-old over to mine and he was showing me an exercise they teach you when you first learn to play piano – rolling your knuckles over the black notes.
.”Suddenly it all connected in my head. This song uses the same notes and construction that that four-year-old showed me.”
Jamie is also going on tour in the UK next month, starting in Cheltenham on May 2.
