You’re right after all, maybe not. I saw a 90 year old woman playing the piano last month, and not an easy piece at that, even if you could tell her hands were not as nimble as they used to be.

But still, you never know what your body’s going to throw at you in the future.

I never saw this movie, but I know the song. « À la claire fontaine » is actually a very well known traditional song in France, that I think almost any kid could sing to you, the first verses at least. While writing this answer, I was wondering where and when it came from, and that seems to be unclear, but apparently it’s very popular in Québec too.
