I said, "It's alright, I really think I peaked in high school"
         G            D         Cadd9

She said, "How'd we end up in a parking lot in Smithtown?"
    G                D              Cadd9
The morning's on its way to sunrise
         G               D         Cadd9
She said, "The island is long, but life is short in this town

I'm glad we got to redo the time"
