What was the song the kids were singing at the very end of the Kid Nation Finale?

At the very end they show a scene where a bunch of people are singing as song that sounded sort of like, "life is like the rain" but I'm not sure those are the correct lyrics! What is the song and who sang it?

I think it was "life is like the wind, always changing, never complaining about good will..."

im not sure what song it is.. I was trying to find it t0o.

And I really can't find anything. Maybe they made it up?
