Elvis Presley was `preparing for UK tour` when he died

London: Singing legend Elvis Presley's ex-wife Priscilla Presley has claimed the singer was preparing for a UK tour when he died.

The 'Jailhouse Rock' hitmaker passed away in 1977 aged 42 and never performed in UK.

"He was preparing for a tour over here before he passed," Priscilla said.

Remembered as the King of Rock 'n' Roll, Priscilla, 70, thinks he never felt appreciated by critics for being such a revolutionary artist, reported Female First.

"... God I wish people only knew what he would do to be able to get that sound. When you were in the recording studio with him he actually was the producer. He knew exactly what he wanted to hear and what he didn't want to hear. But people don't realise that he was a perfectionist and he lived his music," she said.
