Susie Q’s?

I was recently reminded of a story my mother told me when I was a kid. When she was a young nurse in Owensboro--it was the 1950s--two brothers named Phil and Don Everly came to the hospital to visit their cousin and to play her some music. The cousin was on my mother's floor and she met the brothers. She also told them a story about how she and my dad--just a few nights before--had gone to a drive-in movie. They had fallen asleep and woke up around 4AM; they were the only ones there.  The next thing you know, the Everly Brothers had a huge hit called "Wake Up Little Susie." By the way, my mother's name is Sue and some people used to call her Susie. Now the Everlys did not write that song; it was written by the great team of Felice & Boudleaux Bryant, two people my mother NEVER met. But I've always wondered...
