So as you can see the first bit follows the pattern:
2x Riff 1 + 2x Riff 2 + Riff 3

The two parts with singing follow the pattern:
Riff 1 + Riff 2 + 2x Riff 1 + 2x Riff2 + Riff 3 (there is a little
embellishment here and there)

But on the very last time lose the last five notes of Riff 3 and
sustain the last '1' on the B-string. One other point is when you
play the '2's in Riff 3 sustain the note throughout the sequence.
