but you can simplify it and still get away with it.
[D] [Dsus4] [D] [Em]
The jingle bells are jingling
[F#m] [G6]
The streets are white with snow
[D] [Dsus4] [D] [Em]
The happy crowds are mingling
[D7] [D6] [Am] [Am7] [D9]
But there's no one that I know
[G6] [Edim] [G7] [G]
I'm sure that you'll forgive me
[D] [F#7] [B7]
If I don't enthuse
[G] [Em7] [Edim] [A7] [F#7] [B7] [G/B] [A7]
I guess I've got the Christmas blues
[D] [Dsus4] [D] [Em]
I've done my window shopping
[F#m] [G6]
There's not a store I've missed
[D] [Dsus4] [D] [Em]
But what's the use of stopping
[D7] [D6] [Am] [Am7] [D9]
When there's no one on your list
[G7] [Edim] [G7]
You'll know the way I'm feeling
[G] [D] [F#7] [B7]
When you love and you lose
[G] [Em7] [Edim] [A7] [D] [Bm7]
I guess I've got the Christmas blues
[F#7] [B7]
When somebody wants you
[F#7] [B7]
Somebody needs you
[Em] [Am7] [Em]
Christmas is a joy of joys
[C#7] [F#m]
But friends when you're lonely
[C#7] [F#m]
You'll find that it's only
[F#m7] [B7] [E7] [A7]
A thing for little girls and little boys
[D] [Dsus4] [D] [Em]
May all your days be merry
[F#m] [G6]
Your seasons full of cheer
[D] [Dsus4] [D] [Em]
But 'til it's January
[D] [D6] [Am] [Am7] [D9]
I'll just go and disappear
[G7] [Edim] [G7] [G] [D] [F#7] [B7]
Oh Santa may have brought you some stars for your shoes
[G] [G/F#] [E7] [Bm7] [F#7]
But Santa only brought me the blues
[E9] [E7] [Cdim] [Bm7] [G/B] [A7] [D]
Those brightly packaged tinsel covered Christmas blues
[G7] [Edim] [G7] [G] [D] [F#7] [B7]
Oh Santa may have brought you some stars for your shoes
[G] [G/F#] [E7] [Bm7] [F#7]
But Santa only brought me the blues
