It is thirty years to the day that Elvis finally left the building. On August 16th, 1977, Elvis Aaron Presley died, aged just 42.

Thirty years on and thousands of fans are holding a vigil at Graceland, Elvis's home in Memphis, Tennessee. A tribute concert is planned to take place at his home later today and former wife Priscilla Presley and daughter Lisa-Marie are expected to attend. On Friday ten lucky finalists will take part in an official Elvis Presley impersonator contest, run by Elvis Presley Enterprises.

The Graceland mansion, where the King is buried, attracts 600,000 visitors every year.
