C5           G5
Allie woke up 8AM
G5              fill 1
Graduation day
      D5
And you were standing
                      E5 F5
On the hood of the car

Singing out loud
          G5 
When the sun came up.

Chorus:
       C5
And I know I wasn't right,
 G5             G5   fill 1  
But it felt so good

(repeat this for the rest of chorus until)
 

D5                      E5 F5
And three and a half minutes
G5
It felt like a lifetime

(Now those are the main parts of the song, just repeat them as necessary!
The bridge is played only on an electric, and sounds kinda weak acoustic,
so you might wanna play it using barre chords instead of octaves) 

Here's the riff to the bridge.
 

G | -9--7--5--7--7-7-5--5-5-/-7--7-7----------------
D | ------------------------------------------------
A | -7--5--3--5--9-5-3--3-3-/-5--5-5----------------
