Okay, so, this guy's not that old. Though, he's older than someone you would think would be into the likes of K-On!! At least not into it enough to attempt covers of "GO! GO! MANIAC!" and "Listen!" on a damn ukulele.
You know what? No. I'm probably wrong there. Slightly creepy, openly heretical 60-something year-old dudes probably account for a large percentage of the K-On!! viewership demographic.
Punch that dastardly jump in the face and check out Grandfather Kyon shred Ho-Kago Tea Time up old school Henehene Kou Aka style.
