"I'LL ANSWER EXACTLY HOW MANY ROADS A MAN MUST WALK": The story of Robert Zimmerman's journey from Minnesota to appearing in knicker adverts is going to be told by the man who knows him best. No, not Bob Willis; himself. Bob Dylan's autobiography is due to appear on October 12th. Oddly, while Robbie Williams and Geri Halliwell have both managed to turn 'I was in a band; I went solo; boo-hoo' into two volumes of autobiography already, Bob seems to think his long career of actually achieving stuff only requires three books. Funny, that.
