Wogan was a chat show on British television, hosted by Terry Wogan from 1981 to 1992. December 6, 1985 - Jim Henson appears and talks about Lena Horne being one of the first guests, making Kermit and his evolution into a frog for The Frog Prince (although he actually evolved to a frog earlier). Kermit talks about being 30, his relationship with Miss Piggy and Jim being someone he doesn’t talk about – he can't handle it. Joni Mitchell is also a guest. A clip of the appearance, where Kermit is talking about how important Jim Henson is in making him a success, was featured in Being Elmo: A Puppeteer's Journey.
