G
Oh, the weather outside is frightful,
        D
But the fire is so delightful,
    Cadd9                   Am
And since we've no place to go,
        D           Cadd9        G
Let it snow, let it snow, let it snow.
G
It doesn't show signs of stopping,
      D
And I brought some corn for popping;
    Cadd9                      Am
The lights are turned way down low,
        D          Cadd9         G
Let it snow, let it snow, let it snow.


D
When we finally kiss good night,
         Cadd9      G          D
How I'll hate going out in the storm;
D
But if you really hold me tight,
Cadd9       G            D
All the way home I'll be warm.
G
The fire is slowly dying,
        D
And, my dear, we're still good-bye-ing,
    Cadd9                  Am
But as long as you love me so.
       D            Cadd9        G
Let it snow, let it snow, let it snow


Solo Part -Improvise-

D
When we finally kiss good night,
         Cadd9      G          D
How I'll hate going out in the storm;
D
But if you really hold me tight,
Cadd9       G            D
All the way home I'll be warm.
G
The fire is slowly dying,
        D
And, my dear, we're still good-bye-ing,
    Cadd9                  Am
But as long as you love me so.
       D            Cadd9        G
Let it snow, let it snow, let it snow
       D            Cadd9        G
Let it snow, let it snow, let it snow
