^that would be the chorus^
thats roughly the song, i think the chorus is a little off
but my immature skills cant comprehend what jimmy page does,
but i think its pretty good compared to other tabs tho.
there are mandolin parts that other tabs have
transcribed for guitar but i didnt wanna steal
there tabs so i left the mandolin out. hope it helps
