It's pretty easy. Don't need a six (or even a five). A 4-string in drop-D is adequate, and that low D only comes into play once the solo is done.
The bass seems to be easier to pick out on Score than the studio recording, so that might make a better guide. Can't remember the mix on LSFNY.
The verse, off the top of my head:
D-F#-G-D-(C# as a leading tone)-B-A-G#-A
Prechorus/chorus:
G-A-D-(C#)-(B)-(A)-G-A-D
That's the gist of it. there are fluorishes ansome slightly more complex bits, but that's most of the basic outline. I don't remember that bridge/solo off the top of my head, though most of what is under the solo is in B minor.
