Unconfirmed sightings aside, Elvis Presley lives on for millions of his fans worldwide, and in cities across the globe many are getting ready to celebrate the King's 75th birthday on Friday.

The biggest party will be here in Memphis, where January 8, 2010 has already been proclaimed Elvis Presley Day, and events including live music and exhibits are planned.

But celebrations are also happening globally, with Presley fan clubs organizing events in Tokyo, London, Paris and elsewhere.

The most hardcore will be flocking to Memphis, where his ex-wife Priscilla and daughter Lisa Marie Presley will take part in a birthday cake cutting on the sprawling front lawn of the King's former home, Graceland.

"Elvis continues to be popular all over the world, and fans tend to come on the five-year anniversaries," said Graceland spokesman Kevin Kern.

Opened to the public in 1982 and declared a national monument in 2006, Graceland draws nearly 600,000 visitors a year, making it one of America's most visited homes.

In honor of the King's birthday, the estate will unveil a new exhibit entitled "From Tupelo to Memphis," chronicling Presley's early life from his birth in small-town Mississippi to his high school graduation in Memphis up to just before he stepped into the international spotlight.

In downtown Memphis, pastry chefs at the historic Peabody Hotel will serve up a chocolate birthday cake layered with rich peanut butter and sliced bananas, mimicking the fried peanut butter and banana sandwich said to have been one of Presley's favorites.
