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.
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 met Paul Kossoff for the first time when I was playing in the back of a pub room in Finsbury Park in London in 1967. It was kind of a blues thing going on, and he came up and said, 'I'd like to have a jam.' So he came up and jammed with me, and I just loved his playing right from the start.
