Award Snub: He was nominated for fourteen Grammys, but only won three--all of them in the Gospel category. Two of them for the same song.
Covered Up: "Hound Dog" was originally performed by blues singer Big Mama Thornton.
"Blue Suede Shoes" is another one; it was actually a big hit for Carl Perkins before Elvis' own version was successful.
Presley was also late to the party in recording "Shake Rattle and Roll"; his version actually combines elements of the previous hit versions by Joe Turner and Bill Haley (Turner's lyrics, Haley's arrangement).
