When it was a new song I never saw an explanation of the section:
Some may come and some may go
He will surely pass
When the one that left us here
Returns for us at last
We are but a moment’s sunlight
Fading in the grass.
-——But sometimes the word “one” was changed to “wind.”
Today I found this——ahem——NPR article on it. (Sorry.)
They said it was “the hippie national anthem” to some.

I was 17 in 1967 when that song came out and it was the first time I ever saw real hippy's (as it was spelled then) with long hair, sandals and all. It was a real eye opener to me. I remember my Dad, a WWII vet, spotting a long haired guy walking down the street, saying "He looks like Jesus Christ himself."
