I was a kid from Oklahoma who never wanted to be a singer, but was told I could sing. And things snowballed.
I always thought that Elvis could have been a great actor, and that he was put in a lot of unimportant movies when he could have done a lot of great ones.
I think that one of Elvis' charms was that he could sing almost any kind of music. I am sure that in his heart, which I don't know what was there, but just from his singing I could feel that he was very partial to gospel music.
