This song is done completely in power chords to make it easy.
The earlier version was way too spaced out, this goes with the song's timing.
Have fun

            B5
This is the first night, of the rest of our lives.
  B5/Bb     Ab5                 E5
I can't help wonder, "How is it we're still alive?"
B5                                B/Bb5       E5
Welcome to the first night of the rest of our lives.

Oh yeah, and I said

Welcome to the first night of the rest of our lives.
B5                           E5                      Ab5
We stayed up all night long, laughing singing in the streets.

Oh yeah, you know.
B5                              E5                          Ab5
The Clash, Ramones, The Pogues. Our voices hoarse are bodies weak,

And ready for sleep!!!
F5                                    E5          
Lean against me, wipe your blood shot eyes, as I wipe mine.
F5                                      E5(pm build)
From these rooftops, we'll watch the sun rise, Ain't this the life?
              B5
Yeah it's the first night, of the rest of our lives.

B5                                B/Bb5       E5
Welcome to the first night of the rest of our lives.
B5 hold                     E5 hold      Ab5    E5 hold
With just half tank of gas, 150 miles to go. No cash, no food.
B5 hold                 E5 hold          Ab5 hold
We turn the engine off, every time we go down hill.
         E hold
And it's on with the show.
F5                               E5  
I don't know whether to laugh or cry. Oh no, I don't.
F5                      E5(pm build)
All i know is that I am alive, I'm really alive.
             B5
And it's the first night, of the rest of our lives.
  B/Bb5      Ab5                E5

Oh yeah and I said, welcome to the first night of the rest of our lives.
                        Ab5
We heard you there, and jumped from the train.
B5                E5
Ran up the track, all the while you're screaming back,
F5                     Ab5                   B5
"Kiss my ass!!!" We're living our lives, I'm livin' yeah.
