Jesse talks with Paul Shaffer, David Letterman's former bandleader and the co-writer of the disco smash "It's Raining Men." They'll talk about his work on SNL and his role in co-founding the Blue Brothers. Plus, how weird it feels when a thing like the Late Show, something you worked on every day for almost half of your life suddenly comes to an end. Then, children's author Javaka Steptoe, talks about his Caldecott winning book "Radiant Child." Plus, British documentarian Louis Theroux on the craziest day of his career, and Jesse has some real talk about John Wick 2: it's the best six bucks he's ever spent. No contest.
