Through the years, Bob Dylan's dealings with the public have been difficult.
Hear him live and he can be a mumbling and aloof musician -- as at his recent Merriweather Post Pavilion concert.
Riffle through interviews with Dylan on YouTube and you discover a contentious, pretentious artist who is laconic, distant, apparently indifferent to enunciation, pleasantries and other everyday social constructs.
But listen in on Dylan's weekly satellite show, "Theme Time Radio Hour" on XM Radio-- now in its second season -- and you discover quite a different Dylan. He's voluble, generous, articulate. He's liable to quote a poem, give tips on hanging drywall, pass along a recipe. In his show on baseball, he broke into "Take Me Out to the Ball Game" -- a cappella.
