I actually bought an applause tenor ukulele w/pickup a year or so ago after seeing that video (amongst others) on youtube. Had tried a couple of times to learn guitar in the past without much luck, so I figured learning an instrument with only 4 strings instead of 6 would be easier. It is somewhat, but not easy by any means.
Dang he's wicked I came across this Video of Jeff Healy Playing the same some I'm not sure if Jeff wrote "While my guitar gently sleeps" but here's a link to a video of him playing it. Jeff Healy is right up there with Stevie Ray Vaughn and Jimmie Hendrix on playing the guitar.
