《Blue Moon》的英文詞曲是由Jerry Leiber、Mike Stoller所寫，由歌手Bobby Vinton演唱。
歌詞如下：
Well, it may be a blue moon, baby
But I still feel the same
Now that I've seen you again
After all these years
You were the apple of my eye
The one I wanted to marry
And I still feel the same
About you as I did back then
Now it may be cold outside
But let's keep this fire burning
It was just a long time ago
But it seems like forever
And though I've tried to forget
You're still the only girl for me
And though it may be a blue moon
It's still a chance to say goodbye
I remember when we danced
In the candlelight
And how you looked that night
It was a dream come true
And though I've tried to find
Someone new to hold and kiss
You're still the only one
And though it may be a blue moon
It's still a chance to say goodbye
Now don't say goodnight, just say goodbye
Don't say goodnight, just say goodbye to me
Don't say goodnight, just say goodbye now baby
Just say goodbye now baby, don't say goodnight now baby.
