Sir Tom's shock at meeting Elvis Presley

Sir Tom Jones is taking part in an Elvis Presley tribute event on Sunday

Elvis Presley greeted Sir Tom Jones by singing one of the Welshman's songs during their first meeting.

Sir Tom, 70, told Chris Evans on his BBC Radio 2 breakfast show that Presley had asked to meet him when they were both at a film studios in California.

The Pontypridd-born singer said the pair became friends and stayed in touch with one another until two years before Presley's death in 1977.

Sir Tom is taking part in a Presley tribute event in London on Sunday.

"I was at Paramount Studios talking about a song for a film, and they said 'Elvis is here and would like to meet you'," said Sir Tom.

"I said 'My God', I didn't know that he knew that I even existed because it was my first year.

"I went on set and he was there filming and then he stops for a minute and is walking towards me, and I had a ballad out at the time called With These Hands and there comes Elvis Presley singing With These Hands walking towards me, it was like a dream, and I thought 'My God, this is unbelievable'.

"When he got to me he said 'how the hell do you sing like that?' and I said 'Well you're partly to blame'."

He is taking part in Elvis Forever, a concert at Hyde Park on Sunday to commemorate what would have been Presley's 75th year.

It will be hosted by Evans and broadcast live on BBC Radio 2.

Sir Tom has been enjoying chart success with his latest studio album, Praise and Blame.

His new gospel and blues-inspired album sees him exploring issues of faith, sin and redemption.
