Most people my age, their musical life ended in the '80s. They stick with what they know. But my tastes are much broader. And I don't want to stop learning.

Getting to No. 1 makes everyone feel better; of course it does. But it's swings and roundabouts with these things. Sometimes you make a great record, and it clicks with people. And other times it passes them by; there's nothing you can do. It's still the same record.

I'm sure there's a subconscious 'go for it' thing with turning 50. You want to do as much as possible and there are thoughts of how little time we have on the planet. For a lot of musicians in their 50s, the best days are behind them. I'd like to try and show that there is a future.

Of course I'm proud of what I've done, but I'm interested in what's next. I want to be relevant now, in 2012. I've done my bit for the past. I've only ever been about what's next, really, and I'll be that way until I keel over.

And, you know, money is - the money edge is really dangerous to democracy. Because what you have right now - people have said to me that, look, you'll always be outspent, so how can you ever win?

This country has always been run by elite, and it's an elitist democracy. And that's not a radical concept. It's elitist democracy. When people talk about democracy, they don't talk - really talk about participatory democracy, until the point that we get us at Election Day.

Our constitutional system is defined by a balance between the public's need for transparency and the government's need to have a zone of secrecy around decision making. Both are important, yet they are mutually exclusive.

During my years of services in the government, I have spent a great deal of time studying and managing the spectrum of threats to our borders as well as the diverse ways in which those threats are moved across the border.
