Probably a better overview of what Brand is saying, and perhaps the reason that he was on BBC, was his column as a guest editor of the New Statesman. It can be found here:

As for what he says, he didn't lose me at the first 'I don't vote', but by about the third time he stated proudly that he never has voted, I was weary of what he had to say. At that site there is also some interesting rebuttals to Brand.
