forget about the 8th fret, use the 7th fret, standard tuning.
I'll give it one more shot at describing
If you capo the 7th fret, and play the formation like you were playing G, it would actually be D and play it like you were playing C, it would be the G.
The actual standard song intro is in D and G, with the capo at 7th to get that D, you would play it like G. To get the G, you play it like C.
meaning (lo-hi) 230022 is G standard. If you play (lo-hi) 230022 with a capo at the 7th fret it is a D.
(lo-hi) X32010 is a standard C, right? well if you play that formation with the capo at 7th, it is a G.
That's what I mean by chord formation, maybe I am using the wrong term.
The guitarist was probably using a guitar tuned down 1/2 step, so he capoed the 8th, forget about that, it's just uneccessary to worry about. Use the 7th in standard tuning. much more simple.
Since the intro is in that upper register ahead of the capo, you don't change the notes of the intro, you just subsitute the formation in which you play those chords after playing the intro notes.
I have played the song, as I described, before, it gives it a cool sound on the intro, but you lose the lower register on the verses because of the capo.
the actual song intro is
D
G
Bm
A
Cvariant? dont know the name
with the capo at 7, you play as if you are playing these chords
G
C
Em
D
F variant
I would play that last F variant like this (hi-lo) X03213
That's about the best I can do.
