Another little Tidbit...
During the late 60's on Heehaw, I saw Don do a turnaround on "My Heart Skips a Beat". It was a combination of a major and pentatonic minor scale.

See there's another derivative of that lick I was talking about earlier
Oh and I found the video, the turnaround starts at 0:59
