sing a sad song lyrics

Sing me a song of sadness and sing it as blue as I feel
If a tear should appear it's because he's not here sing a sad song and sing it for me
He's unhappy with me he told me so I'm unhappy without him and I still love him so
Oh sing me a song of sadness pretend it's the end of the world
Sing it sweet and sing it low and then I'll have to go
Sing a sad song and sing it for me
[ piano ]
He's unhappy with me...
