White Christmas lyrics

I'm dreaming of a white Christmas
Just like the ones I used to know
Where the treetops glisten
And children listen
To hear the sleighbells in the snow

I'm dreaming of a white Christmas
With every Christmas card I write
May your days be merry
And bright
And may all your Christmases be white
