So, in some ways, the political songs tend to be a bit more like reportage, whereas the love songs tend to be like novels, you can pick them up off the shelf and go into them any time.

Going for constant growth is not actually delivering a decent standard of living and the prospect of your children having a better life than you do. That is the key thing that politics needs to deliver: a better life for your children. That's why people are taking their lives in their hands and crossing the Mediterranean and the English Channel.

An isolationist America is no bloody use to anyone.

But, in the end, even a song that's as politically bland as Blowin in the Wind, you probably wouldn't get up and sing that now, whereas some of Bob Dylan's love songs that were contemporary with that, like say Girl from the North Country, you can still get up an play now.

You have to recognise your responsibility to your community for your actions. Liberty doesn't mean that you are not held accountable. Without accountability, there can be no freedom. I know it seems like a paradox.

Even with politics, stuff comes around again. Woody Guthrie would recognize America today.

If we think we're a nation with great ideas, and a nation that wants to make the world a better place, let's commit ourselves and involve ourselves with our European partners.
