When I was a kid, the world was such a big place, and I had no idea that I would be afforded these great moments in between doing what I love to do.

I'm not interested in being known as the singer from Led Zeppelin.

Don't be hard on yourself. And take as many chances, risks, as you can. You've got to be out there adventuring with the voice. Because if you're just a singer for the sake of it, it's not quite enough.

No matter what we say, entertainers are usually quite insecure, wobbly characters underneath, and maybe that bit of glory or that bit of expression or whatever it is compensates in some area.

I may as well do everything as if it’s brand new, and if I start to feel that any of it’s a compromise, then I’ll...I’ll be in Wisconsin.

I'm a grandfather now.

I think I surprise myself.
