Don't worry, you are not mistaken - this is for uke, transcribed from a guitar tab I have. I think this is even more fun to play on the ukulele. Written by Marcel Dadi, the French fingerstyle legend, who died in a plane crash only 44 years old. Watch the master himself play this on your favorite video channel (and on the wrong instrument).
Regular gCEA (works well in low G)
Here is one to brag. The tune starts off very slowly and increases speed with every repetition. Lots of pulling-off.
P.S. Fixed a little mistake.
