move it to a different key (it sounded alright to me last time I
played it to the record - see what you think)

               Riff 1    Riff 2                          Riff 3
..............|------|..|------|...........|------------------------------|..

E|---2--0-0---2--0-0---------0---------0----0------0------0------0------0---|

So as you can see the first bit follows the pattern:
2 x Riff1 + 2 x Riff2 + Riff3

The two parts with singing follow the pattern:
Riff1 + Riff2 + 2xRiff1 + 2xRiff2 + Riff3 (there is a little
embellishment here and there)

But on the very last time lose the last five notes of Riff3 and
sustain the last '1' on the B-string. One other point is when you
play the '2's in Riff3 sustain the note throughout the sequence.
