Sometimes you write a song in a certain era and it's got a certain kind of significance.

I'm not religious, but I'm very spiritual.

Songs have some kind of structure that connects with people`s hearts.

It was Elvis who really got me hooked on beat music. When I heard 'Heartbreak Hotel' I thought, this is it.

For you know that it's a fool who plays it cool, by making his world a little colder.

I think it's something to do with the structural quality of the songs. We weren't actually trying to make stuff that was cool, or of the moment, although a lot of it was. We were trying to make stuff that was good enough to stick around and lo and behold, it has.

It's not unusual for writers to look backward. Because that's your pool of resources. If you were to write something now, I bet there's a pretty good chance you'd call on your teenage years, your experiences then, stuff you learned then.
