The former Dr Feelgood guitarist announced in January that he'd been diagnosed with terminal cancer and had decided not to undergo painful treatment, opting instead to work until his health forces him to stop.

Doctors had told him he'd be gone by the autumn � but he's still going strong and recently recruited Who vocalist Roger Daltrey for what will be his final album.

Johnson says in the DVD interview: "My future self is quite close to me now � I mean, I'm not going to get much older. Now I'm going to die, you find yourself in a retrospective kind of mood. It's all you can have, isn't it? It's all behind you, mate!"
