Photographer Tony Sacchetti has been taking pictures of Elvis Costello onstage and off it for more than 40 years.
His shots have appeared everywhere from Costello fanzines and his fantastic Instagram page to official Elvis album booklets.
Tony tells me about the art of music photography, covering memorable Costello gigs and his interactions with Elvis over the years.
And, of course, Tony adds six of his favourite EC songs to the playlist.
