Sam is the first person in history known to have earned a doctorate in 'ukulele!
Here's Sam's doctoral thesis. I can't wait to read it...
And if you don't know Sam and her work, here's her website. I'm working through a couple of her Studies books with my students who've suddenly developed an interest in classical music. Her arrangements are really great. Link
(And btw, Sam's Little Book of Giulani does not contain The Four Seasons...)
