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\-----------------------------------|

Repeat this as many times as necessary.
