The first thing you've got to do is put a capo on the 7th fret. The action then
takes place on Em.

I don't know exactly what he does, but he kicks off like this:
                                                     
E-----7-------------7---------|----7-----------------------
B-----8-----8--7--8---10-8--7-|----8--8--7--8--8--7--------
G-----9-----ADD SOME----------|----9--ADD SOME  -----9-----
D-----9-----NOTES  -----------|----9--NOTES HERE--------9--
A-----7-----HERE IN-----------|----7-----TOO---------------
E--7-----7--E CHORD-----------|-7--------------------------

This is something he uses very often:
 
E-------------------------
B-----8-------7-----------
G--------9-------9-----9--
D-----------9-------9-----
A--7----------------------

Just listen to the song and play together with Quorthon, you'll end up
playing pretty much like him.

Then you can play B in the keyboards to add a bit of atmosphere,
particularly in the later stages of the song.

I know this is not exactly much and I'll try to put the entire song on tab when
I have the time.
