I can speak French, understand Gaelic and know my history. That's the training music has given me.

People are people, and I get a bit annoyed that the music business only focuses in on the big metropolises. I find that people that don't live in big cities are just as likely to enjoy music as people that do live in big cities.

I have never had a man give me money. I've always been the provider. I have always been the one who went out and earned, and I've never felt unequal in that way.

'Vagabond' is about owning where I come from, understanding the real power music had to transport myself with, whether that's busking in Europe or getting number ones.

A couple of taxi drivers have asked me if we can survive financially as an independent nation. I say, how come we are more stupid than Denmark or Finland or Sweden? They've all got the same amount of people. Are we all going to down tools? Is everybody in Scotland going to stop working?

I'm not really clear what the whole deal is with flags. I like my flag, but I wouldn't die for it. There's issues of identity, of course. That's going to always come in. I, for example, don't want to be called a 'North Britisher.' I want to be Scottish.
