AC/DC never really bothered to tune up before recording an album, so you may
have to tune down a quarter step or so to get to the right place.


Intro Chords:

+-----------------------------------------------------------------------
+-----------------------------------------------------------------------
+-4-2-------------6-----------------------------------------------------
+-----4-2-0-------6-----------------------------------------------------
+-----------2-0-2-4-----------------------------------------------------

And you're back where you started.

Near the end it does this for a while:
+-------------------------------------------------------------
+-------------------------------------------------------------
+-8-------6--5------------------------------------------------
+-8-------6--5------------------------------------------------
+-6-------4--3------------------------------------------------
+-------------------------------------------------------------


That's about it.  It takes a while to get the picking and fingering right
in the walking part.  I keep my middle finger on the 2nd fret & pick
alternately down & up.

The spacing of the notes kind of reflects the timing of the song, but not
very well.
