Sing a sad song

Sing me a song of sadness
And make it as blue as I feel
If a tear should appear
It's because she's not here
Sing a sad song and sing it for me.

She's unhappy with me
She told me so
I'm unhappy without her
And I still love her so.

Sing me a song of sadness,
Pretend it's the end of the world
Sing it soft and sing it low
And then I must go
Sing a sad song and sing it for me...
