Bm                    A
On my first day back, first day back in town
Bm                              A
First day, my first day back in town
    Bm                        A
The clouds up above, they were humming our song
Bm                   A
Humming, humming our song

Bm                 A
My biggest fear is if I let you go,
G                             F#
  You'll come and get me in my sleep
Bm                 A
My biggest fear is if I let you go,
G                             F#
  You'll come and get me in my sleep
          Bm    A   Bm     A
Come and get me.

  Bm             A
I set my course, sailed away from shore
Bm                    A
Steady, steady as she goes
  Bm                  A
I crash in the night, two worlds collide
    Bm                             A
But when two worlds collide no one survives no one survives and
    Bm                   A
The reddest of reds, the bluest of blues
    Bm                    A
The saddest of songs I'll sing for you.

Bm                 A
My biggest fear is if I let you go,
G                             F#
  You'll come and get me in my sleep
Bm                 A
My biggest fear is if I let you go,
G                             F#
  You'll come and get me in my sleep

(Bm and A until end)
Come and get me. Come and get me in my sleep.
