Ok. I tried all the other intros to back in black and they all don't work.
Here's the right way to play it.



----------------------------3-0------------------------------
--------------------------------3-0--------------------------
--------7-7-7-------------------------2^3R2p0----------------
--2-----7-7-7----7-7-7---------------------------------------
--2-----5-5-5----7-7-7---------------------------------------
--0--------------5-5-5---------------------------------------

-------------------------------------------------------------
-------------------------------------------------------------
--------7-7-7------------------------------------------------
--2-----7-7-7----7-7-7---------------------------------------
--2-----5-5-5----7-7-7---------------------------------------
--0--------------5-5-5---7-4-7-5-7-6-7-7\--------------------

See? it's better than the others and easier.
Another part goes like this:

-------------------------------------------------------------
-------------------------------------------------------------
-------------------------------------------------------------
-------------------------------------------------------------
0-5-4-2-4----------------------------------------------------
----------4---7-5-7-6-7-7\-----------------------------------
