As for the song the nun sang in Airplane, I'm sure it was a Peter Yarrow song, and I think it was "River of Jordan."

There is only one river. There is only one sea.
And it flows through you, and it flows through me.
There is only one people. we are one and the same.
We are all one spirit. We are all one name.
We are the father, mother, daughter, and son.
From the dawn of creation, we are one.
We are one.

Not one of Yarrow's more profound songs, I dare say.
So, do I win a prize, or is this when people start throwing the rotten vegetables at me?
