One of my guitar students here in Vancouver just celebrated the birth of his first granddaughter and requested a solo fingerstyle arrangement of "You Are My Sunshine" that he could learn to play for her.
This one is fairly easy. The melody is the same each time around, though I have made the arrangement get a little more complex the second time through, adding some additional harmony to make it more instructive for guitar lessons.
I made a video for this one so you can see the way it's played. I hope to make more videos of the other fingerstyle guitar tabs I have over time.
The tab is below along with the Youtube video lesson.
