This Friday marks the 47th anniversary of Elvis Presley’s death at age 42, which means that it is Elvis Week, a weeklong celebration of the late King of Rock and Roll at his Graceland estate in Memphis, Tenn. Presley may have left Earth decades ago, but he’s still a household name and an enduring American icon. More than that, Audacy reported earlier this year that fans are still paying big money for Elvis memorabilia – $150,000 for a pair of his blue suede shoes. Why has our love for Elvis stood the test of time? We reached out to Sally Hoedel, author of “Destined to Die Young” and other books about the King to find out.
