I play the uke too! lol... Learned as a young child and moved on to the guitar in my teens, but have two ukes in my guest closet - one of them my dad's Martin bought in 1951. I often use uke chordings on my guitar to sing the old songs my parents sang when we were growing up. Have fun! and will head off to check out this site.
edit: I just posted him to my facebook page! Can't understand a word he's saying (I'm hard-of-hearing), but the melodies are sweet. He's so Cute!!!
