it's easy to figure ou where these riffs go. you just have to listen.
riff 1               riff 2
a2---0---2---0     g 2---0--2---0      a 5-0-3--5-0-3  a 2---0 2---0  a 5-0-3-5-0-3-
e--2-------2--     d --2----- 2--                      e --2-----2--

5--0--3 (that's the nd of the solo.
riff 1 and 2 end with   a 222                  e 2 hold that out.   it's complicating, sorry it's right though. thanks, steph
