Ukuleles: Automatic Happiness!

You've probably heard the Champs' classic '50s instrumental "Tequila." You haven't heard it like this before, though. Props to this guy, not just for his awesome playing and his wall of cool instruments behind him, but his epic vocal interjections!

The chords (if not the tabs), translated from the comments on the video:

The chords are almost always F and Eb alternates.

At the Bridge: G # and F 3 times then G and C.
