Who hasn't taken a walk down Lonely Street and checked into "Heartbreak Hotel"? Elvis Presley's suggestive, dynamic hit single is the subject of this episode from the "Impact: Songs That Changed the World" series. The program explores the 1956 rock 'n' roll hit and how it came to define (partially, at least) the King's enduring appeal. 36 min. Soundtrack: English Dolby Digital stereo.
