on the album version, it starts in Eb. After the harmonizing intro section, there's that
section before they start singing the lyrics. They change to D for this section. And
last part, where they sing the words, it is in E.
not too hard to pull off if you have it in open D
or if you're using barre chords, tune all your strings down a full step.
i don't use the open tuning, just to get a different sound. so, i play it like this.
all chords are relative to the guitar being tuned down a full step.
STARTS in the middle of progression like this:
F, F, Am, C, DmBb, C7, F, C7
then main progression:
F, Am, C, DmF, C7, F, FF, Am, C, DmBb, C7, F, C7 x4
F, Am, C, DmF
after break, at fast strummed middle section:
E over and over again, till you get the alternating chords:
F#, C#7, F#, C#7, F#, C#7
F#, Bbm, C#, EbmF#, C#7, F#, F#F#, Bbm, C#, EbmB, C#7, F#, C#7 x6
till the very end, then
F#, C#7 x7
then end with F#
