I haven't heard it, so I assume it's not. There's no way in hell the first LP is at least, in that case they're some kind of demi-gods.
Dylan never stroke me as that kinda guy. At least from Earth 2 and onwards he's had a very meticulous vibe going on (minus the heroin).
Put hey, it would be pretty awesome if that was true. This song did strike me as being a bit "looser" in its composition than say "Old Black" or "Father Midnight".
