Intro and verse:

G

(I don’t know what actual lyrics are and they’re kinda hard to hear, but here’s the idea)

We both know
I hope(?) …. winter(?)
All we know

and so on until

I’m over and under
over and under
over and under
over and under
ground (?)
(some misheard lyrics again)
(and again)
I’m over and under
over and under
over and under
over and under

Ground

and this time it’s the little section that starts on the word ‘ground’
it looks like this
