OK, there's really only one spot where I'm sure there's another chord. It's in the bridge ("Toasted by the sun, etc.") I'm in A:
C#7 - F#m - C#7 - F#m
B7 - ?? - ?? - E7
I just stay on the B7, and it sounds OK, but there's meant to be something else in there. F#7 and back to the B7? Not sure.
Thanks for all info.
