Maybe a rather dumb question but while listening to '66 and '67 masters recently I spotted Elvis saying "all right" during the instrumental break on "Just Call Me Lonesome" (which I haven't heard before, at least I couldn't remember).
Days back I listened to the "Spinout", "Double Trouble", "Clambake" soundtrack etc. and of course Elvis uses a lot of "all right"'s during songs.
So when did he begin saying this during the songs (which was the first one?) and when did he stop it?
And no, please don't reply by saying he started with SUN 209.
