I made the decision to take on board the critical feedback. Reviews are something you can easily ignore as a performer or writer but I chose to not ignore them here and I think that I benefited. I think I'm stronger for it - and I have a tougher skin as a result.

But I want to deepen as an artist, and working with Shakespeare definitely points in that direction.

I definitely try to broaden the scope of music. I don't know if it's pop or classical or what, but I'm religiously challenging myself all the time, for better or for worse.

There's no life without humour. It can make the wonderful moments of life truly glorious, and it can make tragic moments bearable.

Climate change has always been sort of my main focus. I think also with [what happened in Fukushima, Japan] there's still a lot to think about in terms of what's coming down the pike into the world's oceans, too.

I don't know if it will be my big comeback, but I think it is a statement - that I am a self-sustaining, vibrant, long-term artist, and I'm not going away! And if you don't give me credit, then the musical gods will!

After years of hotels, I'm horribly inept at cleaning up after myself.
