Bob Dylan a radio DJ? Yes sir, if you have XM radio his one hour long weekly radio show debuted this week. Each show of Theme Time Radio Hour has a theme (this week it was weather, next week Mother's Day) and Dylan provides a commentary that is "uncharacteristically chatty."
Unfortunately I don't have XM Radio, and I don't think I'm curious enough to spend the money to listen to one show, but they do offer a free 3-day streaming trial (see link from web page.)
