Most people who know the song, "You Don't Know Me," probably remember the Ray Charlies version, which may well be the best cover of the Cindy Walker classic. In The Relic, the teenaged Chick Charles plans to play it at a Christmas party for the girl of his dreams, Celeste.
That part of the story takes place in about 1960, two years before Ray Charles released his version, and so Chick keys on the 1956 versions by Jerry Vale and Eddy Arnold. But he is determined to make it his own, to show Celeste the depth of his feelings for her. Of course, it all goes wrong, which sets him off on his tragic journey "between the devil and the deep blue sea."
