Intro: G, Gsus2, G, Gsus2


Verse1: G, Gsus2, G, Gsus2
I've had a fire burnin'
Since the holidays began
I hear it's cold out where you're livin'
But any colder than I've been?

I've been an animal since you left me
I need you wrapped under my tree
My Christmas cheer is here and ready
But where are you to set it free


Pre-chorus:
Em      G
I sit alone
        D               C
By the fire inside our home
G                    D
Outside the snow is falling, and I'm singing


Chorus:
G         Em
Wish as I may
D          G
Wish as I might
G             Em
Grant me this one small wish
D             G
On Christmas night
     Em            C
'Cuz I don't need candy
        D             G
Or the toys from my youth
G            Em
I just want you oh darlin'
D            G
I just want you


Verse2: G, Gsus2, G, Gsus2
I've had a candle burnin'
Hopin' you'll come back to me
I think this may be more than anything
Mr.Santa Claus can bring

I was adorable when you met me
I'm on the naughty list this year
A lump of coal won't do it justice
It's all the loneliness I fear


Pre-chorus:
Em      G
I sit alone
       D               C
by the gifts in our own home
G                    D
You're not a single one, and now I'm singing


Chorus:
G         Em
Wish as I may
D          G
Wish as I might
G             Em
Grant me this one small wish
D             G
On Christmas night
     Em            C
'Cuz I don't need candy
        D             G
Or the toys from my youth
G            Em
I just want you oh darlin'
D            G
I just want you


Bridge:
Bm
