Muppets Are Back: Behind The Scenes With Mahna Mahna [VIDEO]

We are just a few days away from the release of "The Muppets."  I loved "The Muppet Show" growing up, and now it's heading to the big screen.

Yes, the Muppets have had several movies, such as "Muppets Take Manhattan" and "A Muppet Christmas Carol," but this is the first time "The Muppet Show" has been revived since it's original run.

To promote the upcoming movie release, the Muppets appeared on Good Morning America this past week and performed one of my all-time favorite songs, "Mahna Mahna!"  Check out the original version followed by a behind-the-scenes look at their performance on GMA.  To watch the GMA performance, click here.
