D--9--9--x-x---12/9--9---14--14----17/16-17/16---14/12---9--x--|
A--9--9--x-x---12/9--9---14--14----17/16-17/16---14/12---9--x--|
E--7--7--x-x---10/7--7---12--12----15/14-15/14---12/10---7--x--|
(repeat)

Man of madness, who lives in my head, keeping me awake at night he
sits on my bed...

this sounds extremely like the version on Reunion.  I don't have 
the little melody bit down yet, but I will have it soon.

the lead bit is pretty easy, a good lead guitarist can add some 
harmonies and get it down pat.  i've come up with this:
