This week, John Kelly goes to New York to talk to singer/songwriter Elvis Costello, aka Declan Patrick MacManus, about his new memoir Unfaithful Music and Disappearing Ink. It’s almost 40 years since Elvis Costello released his first album My Aim Is True. Since those early punk and new wave roots, he has written a stream of unforgettable hits including Oliver’s Army and Watching the Detectives, and explored many other music genres, collaborating with Burt Bacharach, Paul McCartney and the Brodsky Quartet along the way. The memoir Unfaithful Music and Disappearing Ink looks back on a remarkable life in music, and a serious lineage in the music business, a heritage that comes from county Tyrone originally. His father Ross (who considered himself Irish even though he never lived here) was a jazz musician who sang with the Joe Loss Orchestra and played the same bill at the London Palladium as the Beatles in 1963, while his grandfather Pat was a World War 1 veteran and a trumpet player on the famous White Star Line ships in the 1920s and 1930s.
