Every performer who ever performed in rock and roll or even close to it is lying if they tell you that they weren't influenced in some way or another by Elvis Presley. He turned the world around.
There was a chance for me to write one song for the section where Elvis sat in his black leather outfit and sang the old hits. At eight oclock the next morning I had written Memories.
One of my real goals was to hear someone whistling a song I'd written.
I was out on the golf course, a guy came riding out in a golf cart and said, Did you know that Elvis died? And I just said, Well, there you go. It was like I had kinda been expecting it.
If it was just me and Elvis one on one, which only happened once or twice in the times that I did see him, it was a really comfortable. He was a cool guy. Easy laugh, nice guy.
