NOTE: I think the C barre chord sounds better than the open C chord, but they both work just fine.

C5 A5 G5 C5 A5 G5

C5              A5                  G5
 Just when the days start getting colder
C5             A5                 G5
 I walk the streets I never knew
C5             A5             G5
 There's some words I never told you
     A5         F5              C5
 The sound rings out like the truth
                  A5                   F5
 And if you could see what's come over me
                  C5
 Then you would know
C5                   A5
 Cause I'm walking free
                F5
 The wind at my back
                C5
 Bathed in afterglow
C5      A5               G5
 As I sit here in this dark room
C5        A5                 G5
 All I seem to feel is light
C5        A5        G5
 I see color, I see the maroon 
        A5           F5              C5
 In the blood of this life that's ours
                  A5                   F5
 And if you could see what's come over me
                  C5
 Then you would know
                    A5
 Cause I'm walking free
                F5
 The wind at my back

 Bathed in after....
A5         F5   F5       C5
 Watch the sun paint an orange sky
A5      F5        F5       C5         A5 G5 F5  A5 G5 F5 
 Lay me down and feel the days gone by-y-y
C5              A5    G5                   F5 F5
 Just when the days, just when the days, oh
C5              A5                   G5
 Just when the days start getting longer
C5            A5                 G5
 I walk the streets I never knew
     A5        F5       C5
 The sun comes out for you
                  A5                   F5
 And if you could see what's come over me
                C5
 Then you would know
                    A5
 Cause I'm walking free
                F5
 The wind at my back
                 C5
 Bathed in afterglow
                    A5
 Cause I'm walking free
                F5
 The wind at my back
               C5
 Bathed in afterglow, oh, oh
