Rowlf Plays the Minuet in G Major on Muppet Show

Nothing like starting your morning with a dog playing Beethoven on a grand piano. It soothes the brain. This performance is from episode 21 of season 1 of The Muppet Show, which was hosted by Twiggy. I have seen Rowlf play so many songs over the years and I have never seen Rowlf so nervous at the piano. Perhaps flashbacks to his days as a student?
