On the movie Jail house Rock when Elvis is singing Baby I Don't Care outside by the pool one of his guitar players has no sunglasses and then a second later he has sunglasses on. Now how to find it. The guitar player I am talking about is Scotty Moore (if you are an Elvis fan you will know who he is) to the right of Elvis' shoulder. He is sitting on a chair playing the guitar with no sunglasses. They take the camera off Elvis for a second and the next second it is back and Scotty Moore has on black sunglasses. Good Luck!!!
