This is Graffiti 6- Free. It's a really great song! No capo needed. Standard 
tuning. I'm not supplying the lyrics but I'm giving you a video to practice with.

This acoustic version is the same as the actual song. I'm pretty sure the chords I 
have are exact. 
I don't all the chord names so I made them up based on the fret their on.

  E:  0-2-2-1-0-0
  F#m: 2-4-4-2-2-2
  A: 5-7-7-6-5-5 
  Ab: 4-6-6-4-4-4
  B: 7-9-9-8-7-7
  G: 3-5-5-4-3-3

Verse: E, F#m, E, F#m, A

Chorus: E, F#m, A, E, Ab, F#m, B, A, E

Verse 2: E, F#m, E, F#m, E, F#m, A

Chorus: E, F#m, A, E, Ab, F#m, B, A, (G, F#m, E x2)

Chorus: E, F#m, A, E, Ab, F#m, B, A, E, F#m, E, F#m, E, F#m, E

That's it. Use the video that I put in there and you'll eventually get it.
