George Harrison. I'd played bass for ages, but as you know, it's not easy to sit and play a song by yourself on a bass and have anyone be able to recognize it. When George Harrison died, I read about how much he was into ukuleles, and I remembered seeing him in The Beatles Anthology videos, sitting on the grass with Paul and Ringo, and strumming a uke. I thought "Hey, they're cheap... you can play chords on it... it only has 4 strings so how hard can THAT be?". So I ordered a dreadful little soprano from Musicians Friend, along with Jim Beloff's instructional video. It was fun, but was a terrible uke, so I didn't stick with it for long. Although from the video I got I learned about Martin ukuleles, and that planted a tiny little seed in my mind. I had always wanted a Martin guitar (preferably an OLD one), but I'm not enough of a guitarist to justify that. But I thought "Hey, maybe I can get good enough on ukulele to get a Martin, and plus, they're probably less expensive than vintage Martin guitars!".
Last January I saw Jake Shimabukaro's youtube video of "While My Guitar Gently Weeps", pulled my cheap little uke out and decided I needed a better instrument. And that pretty much did me in!
