To some extent, the idea that rock 'n roll used to have this sort of free antediluvian identity, frolicking in the 1950s with Elvis or something, is totally wrong. It's insane. Elvis' relationship with Colonel Parker, his manager, was one of the most possibly corrupt, certainly lucrative, and intense business partnerships ever in rock n' roll.
