This is a big, big week for Marc Maron’s WTF podcast. On Monday, he posted his interview with Saturday Night Live creator Lorne Michaels, a longtime obsession of Maron’s. 20 years ago, Michaels let Maron interview for SNL, and Maron has talked about that meeting over and over again, throughout the years, and he finally got to talk about it with Michaels and get some closure on that part of his life. His interview with today’s guest, Elvis Costello, might not have that totemic personal importance to Maron. But then again, Costello has been inspiring smart people for nearly as long as Michaels has, and the two are jointly responsible for one of the great moments in the early history of SNL musical performances. Costello just published his new memoir Unfaithful Music & Disappearing Ink, and he’s got plenty of stories to tell, so this should be a good one. Listen to it here.
