Ah, one of those "easy" songs that overly complicated. I'm not so sure the GD really did it the same way with any real consistency. It is definitely a song that gets played a lot of different ways by bands, especially in terms of rhythm.
As for the F chord in the C chord part of the verse. It is there. No doubt.
As for G>Gsus vs G>C, I play the C.
As for the rhythm, I think there's a consistent difference in the rhythm from the beginning/verses and the end of the song.
The other thing that often gets messed up is the chords of the chorus. I played it wrong for ten years. Lots of folks play
D C G C D
D Amin G C D
as for the "Bams", hit on the 2,3 at the last two lines of the first solo and hit 4,5 at the last two lines of the second.
Fun tune to play for sure.
