The cable channel Antenna TV airs re-runs of the Johnny Carson show every week night. I read the upcoming schedule and the March 1974 appearance of Jim Henson airs Friday night (May 26th). This episode he brought Kermit to chat with Johnny as well as he and Frank Oz did a small bit. Classic Muppets here! One year before the SNL gig and Muppet Show:Sex & Violence pilot! Good stuff!
