I visited People's Music and the word is the ukes are about a week from arriving in the store. Should be soon.
Here's a little YouTube video that's both a lesson (the first part) and a performance appropriate for today by Mike Lynch a man who, like me, prefers homemade music to any other kind.
If Santa brought your family a uke, this Music Teacher Mike is a great resource to check out. YouTube is full of great uke lessons; Mike's lessons are kind of advanced, too advanced for beginners, but good if you've played guitar.
Enjoy, and Merry Christmas everyone!
