Very easy.  It's off if you play along to the actual song but this is far more 
straightforward than any other tab and I think it sounds pretty good.

Strum pattern: D D U U D U

Intro--played like the verses.

D            A       G    D           A G
Last night I fell in love without you.
D                       A        G
I waved goodbye to that heart of mine
        D            A  (and stop it from ringing.)
Beating solo on your lawn

      G      D                G       D
Every aching wound will cauterize and bruise
   A                 C               G
In memory of what we used to call in love
         G         D          G         D
And only time will tell if violins will swell
   A                 C               G
In memory of what we used to call in love
                     D ...start playing the pattern for a verse.
We used to call it love.


Same pattern throughout.

Last night I fell in love without you
The coup-de-grace that set me off
Would've made for decent fiction

Every aching wound will cauterize and bruise
In memory of what we used to call in love
And only time will tell if violins will swell
In memory of what we used to call in love
We used to call it...

Last night I fell in love without you
The stars at night aren't as big and bright
As you make them out to be

And every aching wound will cauterize and bruise
In memory of what we used to call in love
And only time will tell if violins will swell
In memory of what we used to call in love
In memory of when we used to call it love
