Paul Williams is a master storyteller: Oscar and multiple-Grammy winner, actor, hit-maker, composer of everything from “The Love Boat” theme to the immortal “Rainbow Connection” from The Muppet Movie. He’s as busy as ever, costarring in this season of Goliath with Billy Bob Thornton and serving as president of ASCAP, the performers’ rights organization. He’s also a raconteur, and you’ll hear about everything from Orson Welles to Phantom of the Paradise. Leonard and Jessie are still recovering from the experience of spending time with this exceptional man.
