With Free, we had phased out all of the blues material and wanted to phase in all original material, and the only song that stayed from our blues past was 'The Hunter' by Albert King. People just loved that. And I said, 'We have to write a song that will top that - otherwise, what are we doing here?' That was the birth of 'All Right Now.'
I look at John Lee Hooker and Muddy Waters, guys who had a fantastic longevity, and I learned something from them. They didn't try to sell records. They weren't saying, 'Ok, what can I write, what can I do in the studio that will sell?' They were just doing their thing, and people picked up on it. I like the idea of that.
I have a lot of analog. I think a lot of people do. There are a lot of people that are re-discovering it. I still have a lot of my old records from back in the day. It's a joy to play things like Junior Wells' 'Hoodoo Man Blues,' and John Mayall & The Blues Breakers with Eric Clapton. There's a warmth that you can still feel.
