Take a look, it's in a book

I was walking back to my office through the parking lot, after picking up lunch. I saw a butterfly, about 20 feet above me. Simultaneously, as my eyes/brains identified it as “butterfly” (as opposed to, say, “missile” or “777”), the words and tune of “butterfly in the sky…” came to my mind.
