On June 5th 1956, a 21 year old Elvis Presley strutted onto the set of the Milton Berle show.  When Milty introduced Elvis, the future King of Rock and Roll exploded into “Hound Dog.”  Its a performance that changed America.  It helped usher in the sexual revolution, the rock and roll revolution, and launched Elvis as an immortal icon of cool.  The clip, 56 years old on this day, features the aforementioned “Hound Dog,” a funny interview where Elvis gets some digs into Berle, as well as insight into what hair gel Elvis used on his jet black hair.  Its really an amazing slice of history, especially getting a prolonged glimpse at Elvis’s hypnotic stare that practically brainwashed the entire youth the Western World over.  Elvis plays up his role as the coolest, hippest, and coolest king of teenagers, alternating between fits of nervousness, confidence, and uncontrollable sexual desire in the presence of a beautiful woman.  This clip is still incredible to this day and is must watch for anybody with a pulse for rock and roll perfection.
