Just saying in advance that I can't do guitar tabs so I'll put down the notes for 
what the bass is playing because I figured it out on piano. I've put what the bass 
guitar is playing with a * while the rest of the chords are just transitions that 
other instruments would play as well as the chords with the *s; if you just do an 
acoustic version, then disregard the stars and follow all of the chords. Hope this helps y'all!

C* : C-C-C-G-C-G-A
Am*: a-a-a-G-a-G-A ('a' as in lower a note, 'a' as in higher a note)
F* : F-F-F-C-F-C-D

Intro: C F G, Am F G
