Capo 6

This is pretty close to the main riff used in the song. I think
there are two guitars in the intro and it's hard to tell
which is which but this sounds ok.

        A5        G5        C5
Another year has passed us by
         F5         C5          G5
It was gone in a blink of an eye
          F5    C5
We've got 15 bucks
             E5          A5
Seems we're down on our luck
          F5
But who cares
                  G5
You're with me tonight

Interlude: A5 G5 F5

This is our time now

 C5                   G5
When the fire burns out
           E5         F5
And it's only me and you
 A5
Shimmery lights outside
       G5
They reflect your eyes
        F5               G5
As you say "I love you too"
 C5                  G5
When the sun comes up
          E5                 F5
And the snow falls from the roof
        A5     G5        F5
I can smile because I spent my Christmas with you

//Interlude: play the main riff twice, once with C in the background
and the second time with F//

A5       G5           C5
All the shops are closed
        F5            C5          G5
Busy streets never felt more alone
  F5         C5              E5      A5
Everyone around in this crazy-ass town
     F5                   G5
So ready to finally be home
    A5       G5       C5
So I'll sit by the fire
            F5          C5          G5 
Watching re-runs and making you smile
          F5           C5
Sharing cookies you burnt
            E5         A5
You spilt milk on my shirt
        F5
That's okay
                  G5
You're with me tonight

Outro: play the main riff twice, once with C in the background
and the second time with F, then the song fades out. So you need
to come up with a way to end it. I usually just play F, F minor,
and then C and end it on C. Enjoy!
