Sorry, I found some more errors and wanted to send this.  It's as close to the lyrics of "Baby It's Cold Outside" as I could figure:




[HER:]  [HIM]
I really can't stay But, baby, it's cold outside
I've got to go 'way But, baby, it's cold outside
This evening has been                  Been hoping that you'd drop in
so very nice I'll hold your hands, they're just like ice!
My mother will start to worry Beautiful, whats your hurry?
and father will be pacing the floor Listen to the fireplace roar
So really I'd better scurry. Beautiful, please don't hurry
Well, maybe just a half a drink more Put some records on while I pour
 
 
The neighbors might think Baby, it's bad out there
Say, what's in this drink? No cabs to be had out there
I wish I knew how Your eyes are like starlight now
to break the spell I'll take your hat, your hair looks swell
I ought to say no, no, no sir                  Mind if I move in closer?
At least I'm gonna say that I tried             What's the sense of hurtin' my pride?
I really can't stay Oh, baby, don't hold out
Ah but it's cold outside                         Baby, it's cold outside.
 
 
I simply must go                                       But, baby, it's cold outside
The answer is no But, baby, it's cold outside
This welcome has been  How lucky that you dropped in
so nice and warm Look out that window at that storm!
My sister will be suspicious Gosh, your lips look delicious
my brother will be there at the door waves upon a tropical shore
My maiden aunt's mind is vicious Ooh, your lips are delicious
Well, maybe just a cigarette more Never such a blizzard before
 
 
I got to get home  But, baby, you'd freeze out there!
Say, lend me a comb  It's up to your knees out there
You've really been grand                          I thrill when you touch my hand
But don't you see?  How can you do this thing to me???
There's bound to be talk tomorrow Think of my lifelong sorrow
at least there will be plenty implied if you caught pneumonia and died...
I really can't stay Get over that hold-out
 
 
[TOGETHER]

Ah, but it's cold outside!
