This may seem pedantic, but I'm wondering if the original song title was "Anytime" or "Any Time." I see it written both ways, and I think the current trend is to make it one word. (BTW, I've probably 'known' of the song since I was small, but it really came into my consciousness via Arlo Guthrie's version of it on the album "Alice's Restaurant," and it's become a staple of my performing repertoire in recent years.
The reason I care about the spelling is that it can affect searching for the song (lyrics, recordings, etc.) (That, and because I suffer from terminal pedantry.) ; D
