I'd pick Just Pretend with Heart of Rome as a bonus track
What I would do is get the TCB Band together, and have them record some new - backing tracks (with todays modern sound) to some of Elvis' rockers (ex: Blue Suede Shoes, Hound Dog, Jailhouse Rock, Promised Land, Way Down, Burning Love, etc...)
Call the cd...ELVIS2K
