I’ve got all his gospel recordings. Gospel was his favorite music. His favorite singers were baritone gospel singers.
I don’t believe that Elvis ever hid the fact that his spiritual roots were in the Assembly of God Church. Although he didn’t go to church, he was a personal friend of Rex Humbard, who he kept in touch with and who he considered his Pastor. Rex preached his funeral.

JD Sumner was his favorite baritone singer.
