Elvis Costello is one of the most accomplished songwriters of his generation. In his memoir, Unfaithful Music & Disappearing Ink, he details his songwriting process, his encounters with everyone from Paul McCartney to Joe Strummer, and his place in a rapidly changing music industry. Costello is up for a Grammy this week for the audiobook version of Unfaithful.  For the Spiel, a fairly pointless history lesson from Ted Cruz.  Today’s sponsors: Dunkin’ Donuts.
