I don't think this will be his last album, he can't stop writing songs, so, why would he not record them? I think he has been busy over the last few years, apart from his album, there is the auction thing which he must have had a lot of involvement with, the Local Hero musical which seems never ending, the TV show with Brian Johnson, maybe more filming with Henrik Hansen!! We don't really know his full involvement in the Buddy Holly project, plus his own personal life etc. He might be a 'Slow Learner' but I am sure he keeps himself busy. I think only serious ill health will stop him recording.
