Robert Plant was always my favorite singer-and he's said nice things about me, you know.

A lot of people would like to sing like Bing Crosby, but very few could match his phrasing or depth of tone. He's influenced every real singer whether they know it or not. I used to hear Bing Crosby as a kid and not really pay attention to him. But he got inside me nevertheless.

The colored folks been singing it and playing it just like I'm doin' now, man, for more years than I know. I got it from them.

Before Elvis there was nothing.

Amy [Winehouse] changed pop music forever, I remember knowing there was hope, and feeling not alone because of her. She lived jazz, she lived the blues.

Blues was my first love. It was the first thing where I said, 'Oh man, this is the stuff.' It just sounded so raw and honest, gut-bucket honest. From then I started rebelling.
