Agreed. However...... there is perhaps a higher standard when one writes songs as a vehicle for social change. In the same way, I care little if a politician wishes to spend an evening with coke and hoookers. If he spends his working day lecturing the rest of us on family values and drug law then I have a bit of an issue with it.
As I say, with Dylan is really doesnt matter at all. Did you see the fuss people made when they realised that Billy Bragg lives in a fairly large house?
