Although I'm certainly well aware of the context/purpose of this song (which is, to me, one of the nicest songs ever written - although there are certainly many), there's one line in this song that strikes me the most (and kind of "gets to me" every time).
That line is the part about, "..how high does the sycamore grow? If you cut it down....." (etc.)
But, while these lyrics focus on Nature and the Earth (and the creatures and the trees, etc.); while the lyrics are not lost on me, when I heard this song I inevitably think of human babies and children, and about how many - whether anyone realizes it or intends it or not - babies and children are "cut down" long before they, or anyone else, ever gets to see "how high that particular sycamore would have grown". And by "cut down" I don't particularly mean the ending of a life. I mean the tendency of so many people to look for things that are wrong with a child, rather than look for what may be wrong FOR the child. In fact, I mean any number of things that go on with babies/children that amount to their never getting to see "how high" they would have grown had something not gone on that "cut them down" far too soon.
