The intro for the guitar without distortion (Gillian's?) goes:

e------------------------------------------------------------------------------
b------------------------------------------------------------------------------
g------0---0---0--------0---0---0--------4--------4--------4---4---4-----------
d--3-3---3---3---3--2-2---2---2---2--0-0---0--0-0---0--0-0---0---0---0---------
a------------------------------------------------------------------------------
e------------------------------------------------------------------------------

Guitar with distortion (Barney's? -- get your own timings):

e-----------------------------------------------------------------------------
b-----------------------------------------------------------------------------
g-----------------------------------------------------------------------------
d----------------------------------5--3--0--2-2/5-5--5--0--0----------------
a----5--3--0--2-2/5-5--5--0--0----------------------------------------------
e-----------------------------------------------------------------------------

Then there's a couple of seconds of chords, perhaps A and B; listen to the
song for the exact instance of this...
If anyone knows what these chords are or cares [sorry :) ] they can verify this.

The bass portion of this song sounds very simple, no doubt because Peter sings.
