I grew up watching The Muppet Show. My favorite episode was with Alice Cooper. He sang Welcome to My Nightmare. I was blown away. I couldn't believe Alice Cooper was there hanging with Kermit and the gang. Then Blondie did a cameo on that show and my mind was blown. One time I was watching a show with my friend's kid. A dragon had a very familiar voice. Turns out it was James Hetfield! How about Iggy Pop on the Adventures of Pete and Pete? In all honesty that show was on Nickelodeon but it was pretty adult. Here are some awesome rock star cameos on kid shows. Enjoy!
Bonus! Here's one of Alice's performances on The Muppet Show.
