First Angus plays this riff four times : 
 
E--------------------------------------------------- 
B----------------------17------------------------- 
G------14bu16h---------bd14---12---------- 
D---------------------------------------------12--- 
A--------------------------------------------------- 
E--------------------------------------------------- 
 
bu=bend up h=hold bd=bend down 
 
Then the main riff Riff A 
 
E-----------------------------0--3po0--------------------------------0--3po0--------0------------------- 
B------3bu5-------0ho3---------------3po0--------------0ho3---------------3bs---------3po0------- 
G---------------------------------------------------2bu4------------------------------------------------------ 
D---------------------------------------------------------------------------------------------------------------- 
A---------------------------------------------------------------------------------------------------------------- 
E---------------------------------------------------------------------------------------------------------------- 
 
E----------------------------------------------- | --------------------------- 
B---------------4------------------------------ | --------------------------- 
G-----2bu3-------2sb3bd2po0---------- | --------------------------- 
D----------------------------------------2po0 | --------------------------- 
A----------------------------------------------- | --2po0------------------ 
E----------------------------------------------- | -------------2po0------- 
 
The bit on line two to the bar is played twice, sb=bend before 
playing, po=pull off ho=hammer on. 
 
The other main riff....Riff B 
 
E----------------------------------------------- 
B----------------------------------------------- 
G----------------------------------------------- 
D------------------------------------------------ 
A------------------------------------------------ 
E----s3--0---s3--0--0--0---s7--0-0------ 
 
s=slide to note. 
 
The chord thats played over 'you know I love you so' is A7 
 
EADBGE 
x02020 
 
Then it's back to riff B, but play the bottom two strings after the 
first two notes & let ring. 
 
From here it's a lot of repeat stuff.  The next new bit is as follows: 
 
E5  |   E5 F5  |  F5 F#5  |  F#5 G5  |  etc up to A#5 B5 
 
E5 is EAD 
         022 
 
F5 is EAD 
         133 
 
and it slides up from there. 
 
Then it goes G#5 A5 A#5 B5 C5 C#5 D5 D#5 and back to riff A 
 
When it stops and starts again, the riff Angus plays is like this 
 
E-------7po4po0------- 
 
really fast over & over and then goes up the strings as follows E 8 
times, B 8 times, and then GDAE each  four times. 
 
The riffs Angus plays with Bon singing are all basic E pentatonics on 
the 12th fret.  For example the first one is: 
 
G-----14bu16--14bu16---14bu16--- 
 
The second is 
 
G--------------------12bs 
D----14----14-----------------14 
 
The third 
 
G--14sb16--14--12bs------- 
D-------------------------------14 
 
The rest are mostly the same notes, & all Em pentatonic which is 
 
E---------------------------------------------------------12--15------------ 
B----------------------------------------------12--15----------------------- 
G-----------------------------------12--14---------------------------------- 
D------------------------12--14--------------------------------------------- 
A-------------12--14-------------------------------------------------------- 
E--12--15--------------------------------------------
