Below I've placed a couple of videos of a guy by the name of Greg Pattillo playing the opening themes to Inspector Gadget and Sesame Street on the flute.

Before you run screaming in the other direction, which is exactly what I do whenever the possibility of a flute solo lingers around the corner, just let me say you've never heard these tunes performed like this before. This musician melds flute playing with beat boxing, and the result is amazing. That's right: he plays the flute and beat boxes at the same time.
