《Christmas Without You》的詞曲作者不詳，因為這是一首由各種不同音樂家在不同的年分錄製的混合版本。如果你能提供詞曲作者的信息，我可能能更確切地回答。然而，我現在能給你的一些信息是：
歌詞：
(verse 1)
Snowflakes falling, lights are shining,
Merry Christmas, but I'm not feeling it.
All around me, family and friends,
But I'm alone, I'm missing you.
(chorus)
It's Christmas without you,
Underneath the Christmas tree,
It's lonely without you,
All the joy there's no one to share.
(verse 2)
I wake up in the morning, I look out the window,
See the sunshine, hear the birds, but it's not the same.
Without you here, it's just a holiday,
It's not the same, I'm missing you.
(chorus)
It's Christmas without you,
Underneath the Christmas tree,
It's lonely without you,
And I just can't seem to move on.
(Bridge)
Maybe I can find some happiness somewhere else,
Find someone new to love and make them Merry,
But right now, in this empty house, it just doesn't feel right,
I'm wishing you were here under the mistletoe tonight.
(chorus)
It's Christmas without you,
Underneath the Christmas tree,
It's lonely without you,
And I just can't get you off my mind.
