I managed to tab this from some live footage off youtube. It varies every time but here
the main parts.

This is from a chicago gig on youtube so it may not be 100% due to sound quality.

Then on the live versions there is a long coda in which jonny plays the drums in which
bass is playing the same sort of thing as the main riff. On some versions ed O'Brien
with the reverse reverb sound, although it is diffrent everytime and the sound quality 
it hard to distinguish what he is playing.

But here is the main bulk
