Great class today! You may be feeling a little overwhelmed with so much information crammed into such a short time. Don't worry. It will get easier with practice. A little practice each day is more effective than a long practice once a week. Find a place that you can leave your ukulele and book out so that you can pick it up anytime you have a few minutes to spare. When I was a kid, we kept the ukulele on top of the piano.
Here are recordings of some of the songs if you'd like to sing and play along and a link to help you tune your ukulele. Don't forget, "My Dog Has Fleas".
"Clementine"
"Stewball"
"You Are My Sunshine"
