American Old-time song lyrics from www.traditionalmusic.co.uk 
HAVE YOU SEEN YUM-YUM? Copyright, 1886. by F. Harding. 
I must first of all explain that I'm not a bit insane, As you probably imagine from my make-up; But I'm just a trifle mad from the trouble I have had. It has given to my temper quite a shake-up. I once weigh'd sixteen stone, but I'm now all skin and bone, The doctors say that I will never rally; My wife's gone with a Jap, but I wouldn't care a rap, But she's gone to kick her heels up in the ballet. 
Chorus. Have you seen Yum-Yum? she has gone and left her Ko-Ko! Have you seen Yum-Yum? she has left me like a bum! Oh, just to think that Nan-ki-poo with her could play at peek-a-boo, And I've got nothing more to do with Yum, Yum, "Yum. 
When she skip'd the tra-la-loo, she took all my money too, That is very tough I think you will allow, sirs? She sneak'd my watch And chain, which I'll never see again, And she even gave the other bloke my trousers. To think that she, my wife, should disgrace me all my life, And treat me as if I were but a nigger; I'm sure she'll have to pad, and she'll want it very bad, If she ever tries to travel on her figure.-Chorus. 
If I was a Japanese, I would get my snickersnee, I would follow my old woman and her Blo-ko; And the moment that we met, half a dollar you can bet, I would rap him pretty hard upon the Ko-ko. I really cannot say what has made her run away, I always did my very best to please her; Yet away she had to run, with a foreign son of a gun, He's a dirty, greasy, ugly Japaneser. -Chorus.
