Fans around the world are celebrating Elvis Presley's 75th birthday today.

Testament to The King's legend, 33 years on from his untimely death in 1977 he's still one of the biggest earning dead celebrities and adored by fans around the globe.

Earlier today in Sydney, some 10,000 people gathered at a train station for the six-hour 'Elvis Express train' to the town of Parkes where the 18th annual Elvis Festival is held.

His home at Graceland, Memphis is already being besieged by fans desperate to pay their respects to their idol.
