Confused All Over

Dear Editor,
    Did you ever get a tune in your head that just wouldn't go away? Everyone has; it's called, among other things, an "earworm." I have spent the better part of a day with the Sir Douglas Quintet's version of "Shakin' All Over" in my head. But the funny part is: The song never existed. That can't be true, can it? I have searched reams of screens on the Internet, and have come up empty. I have listened to a thousand previews, thinking perhaps someone else did the song I am hearing in my head. That ain't it.
   I am sure if such a cut did or does exist someone in Austin has the record, and can tell me I'm not just wishin' it so.
