Don't think twice, it's alright

G                  D              Em
It ain't no use to sit and wonder why babe
C                  G      D
It don't matter anyhow
G                      D              Em
And it ain't no use to sit and wonder why babe
A7                   D     D7
If you don't know by now
G                             G7
When the rooster crows at the break of dawn
C                        A7
Look out your window and I'll be gone
G          D          Em        C
You're the reason I'm traveling on 
G           D          G
Don't think twice it's alright
