A couple days ago I was trying to remember how to play "Baby Elephant Walk" for a prospective recording project. Turns out this brilliant Brit already came up with an arrangement, which he posted on YouTube: http://www.youtube.com/watch?v=-j-aLze1OCs&NR=1
He also has a great website called Ukulele Hunt: www.ukulelehunt.com, with tones of info, links, vids, and TAB.
There is also a spot for ukers to post TAB-- so I did.
