In 1961, as we all know, Cindy Walker was presented with a demo of "Distant Drums" by Jim which was (allegedly) disregarded by Chet Atkins. Jim then told her to pitch the demo to someone else.

But in 1966, Cindy was asked to go to the RCA studios and upon entering there she witnessed the overdub session of "Distant Drums".

Where did this other copy come from? I wonder if Jim had made two copies of this tape and Mary had secretly kept one?

It's something I've always wondered about.
