Tens of thousands of Elvis Presley fans have arrived in Memphis and are lining up at the entrance to Graceland for a two-day vigil marking the 35th anniversary of his death.

The Rock N' Roll icon died on Aug. 16, 1977, at age 42 of heart disease and prescription drug abuse.

Fans holding candles will be allowed to visit his gravesite at Graceland's Meditation Garden beginning around 8:30 p.m. The vigil is expected to last into early Thursday.

The vigil is the highlight of Elvis Week, the annual celebration of Presley's life and career. Organizers have said they expected 75,000 people to attend Elvis Week, with many taking part in the vigil.
