Guitar Tab and Guitar Chords to Play Away in a Manager

Chords Used: E (022100) | A (x02220) | B7 (x21202)

start song by strumming E chord, then hitting 7th fret 1st string 2x, then 5th fret, then 4th fret 2x, then 2nd fret. (this gives people starting melody notes)

E A E
Away in a manger, no crib for a bed,
B7 E
The little Lord Jesus laid down His sweet head;
E A E
The stars in the sky looked down where He lay;
A E B7 E
The little Lord Jesus, asleep on the hay.

E A E
The cattle are lowing, the poor baby wakes.
B7 E
But little Lord Jesus, no crying He makes;
E A E
I love Thee, Lord Jesus! Look down from the sky,
A E B7 E
And stay by my cradle till morning is nigh.

Grandma Got Run Over By A Reindeer

G
CHORUS Grandma got run over by a reindeer
C
walking home from our house Christmas Eve
D
You can say theres no such thing as santa
G D G
but as for me and grandpa we believe

Em D
She'd been drinking too much egg nog
G
and we warned her not to go
C
but she forgot her medication
G D G
and she wandered out the door into the snow

When we found her Christmas morning

at the scene of the attack

there were hoofprints on her forehead

and incriminating claw marks on her back

CHORUS
It's not Christmas without grandma

all the familys dressed in black

and we just cant help but wonder

should we open up her gifts or send them back !

CHORUS
Now were all so proud of grandpa

he's been taking this so well

see him in there watching football

drinking beer and playing cards with cousin mel

CHORUS
Now the goose is on the table

and the pudding made of fig

and the blue and silver candles

that would just have matched the hair in grandmas wig

CHORUS
I've warned all my friends and neighbors

better watch out for your selfs

they should never give a license

to a man who dirves a sleigh and plays with elfs !
CHORUS
