Need help finding a finale song!!!?

I made a video of my mother's childhood for her birthday and set music up to it. I'm just having the hardest time finding a last song. I'm keeping it a tad old school and about family, growing up, being happy...etc. Here's what I've used so far: In My Life, Blackbird, and Here Comes the Sun by the Beatles, Turn Turn Turn by the Byrds, I Want to Hold Your Hand done by Glee, Somewhere Over the Rainbow, and So Happy Together by the Turtles. Any other ideas?? Thanks!
