My guest this week says he uses music before he sets hands to keyboard, to help conjure the creative mood. Sometimes it works the other way around; he’ll be writing and will realise the mind-jukebox is directing a scene to the structure or lyrics of a song. He trained as a lawyer but quickly found a creative outlet as a legal adviser on TV dramas. From there he began writing some of the UK’s most popular series and is now a crime novelist. Funnily enough, one of his key songs is Jon & Vangelis’s I’ll Find My Way Home, which one of my earliest guests used as a touchstone for his MG novel – isn’t it amazing how one piece of music can inspire such diverse ideas? He is TJ Cooke and he will be here on Wednesday with his Undercover Soundtrack.
