A tour-de-force by Chris in collaboration with arranger and orchestrator Andrew Pryce Jackman who, very modestly, wouldn't take a writing credit, despite the enormous contribution he made not only to this song but the whole FOOW album.
There's an 8-string as well as the Rickenbacker (often present with a lot of fuzz), and from time to time two basses are playing simultaneously; see below.
There are a lot of pace changes but the overall slow crotchet feel meant it seemed right to indicate crotchet tempi despite the preponderance of 11/8 passages (which are basically 4/4+3/8 anyway). Key sigs are sometimes relevant to a root key, sometimes just convenience to prevent too many accidentals. Smaller notes are either ghost bass notes or orchestral elements.
Opening bass (00:27 onwards) - some of those harmonics are very high, and I can only guess that, for example, the G# is being played on the smaller E of the 8-string.
I know the piano part in bar 10 (00:36) is slightly inaccurate.
The 8-string solo is just the upper part - another 8-string continues the riff - but when it gets to bars 65-69 (03:35) both may be duetting. Here, the G string(s) remain open and sustain, and this is shown in the score by note-tails going the opposite way to the other part, which is played on 2nd and 3rd strings. You could do it on a regular 4-string but I found it unsatisfying.
I know that's not a cor anglais in bar 97 (05:12) it's some sort of brass instrument. Don't @ me.
Finale (12:09): as well as a full orchestra and church organ and all sorts of drums and percussion, there are two highly-fuzzed bass parts, and tbh it gets hard to hear anything clearly, so it's hope-for-the-best all the way.
Outro (13:49): famously played on a double-neck guitar/bass with only the guitar pickups on, so the extra harmonics heard derive from the guitar strings; otherwise, it's played pretty straight. And yes, maybe the fermatae could be better placed.
