Sigh, you're right, that is quite old - must be the 80's, or perhaps even the 70's! Perhaps song construction/music theory from those times (and earlier, certainly) is invalid/irrelevant by now, nothing useful there.
It was 1970. I said that in my first sentence. Unless, I've misinterpreted your reply, your sarcasm has missed the spot. I didn't mean it wasn't relevant. I meant it was old. Like... "Grandad" old or "first kiss" old. Not, "it's so old it's irrelevant" old.
Still... a smiley at the end makes it all better.
(**Whistles** "Gonna tell Aunt Mary ..." )
Little Richard - 1956. Very, VERY old! (Ooh, there's that smiley that makes everything alright again.)
