I'm tipping the hat and looking back.

Each album comes from definitely a different period in the evolution of each of us individually as creators and the role that we take in life. The external stimuli changed... so the songs are full of lots of different meanings.

It's a two-dimensional gig being a singer, and you can get lost in your own tedium and repetition.

I don't think I've aged gracefully.

I'm not interested in being known as the singer from Led Zeppelin.

I've lived a life which has been pretty much full up with ambition, ideas, stimulus, creativity, some negativity which I try and avoid.

There's a similarity between European and North African folk musics.
