Alice Cooper on “The Muppet Show”

I am too young to have experienced the beginning of Alice Cooper.  An early Halloween memory of mine is the first time I ever heard or saw him which was on this episode of "The Muppet Show". The episode was a part of season 3 which was 1978-1979.  I don't remember if I saw the original broadcast or a rerun but remember having enjoyed it.  He ended up performing "Welcome to My Nightmare", "You and Me" and "School's Out".  It was a strange guest for the show but after watching it I can see why they had him.  One of my favorites from the classic "Muppet Show".
