Uncle Dave Macon didn't sing this. I'm posting this here only so that the lyrics of the parody will be in the same thread as the lyrics of the original. A guest requested this song in the thread 'Mother Songs' of the tear-jerker variety but it isn't really appropriate for that thread either.

Oyster Stew
Parody of "Just Tell Them That You Saw Me"

Spaeth (History of Popular Music, p. 277) says there were many parodies of "Just Tell Them That You Saw Me." This one, however, is the only one I have collected. It shows a vigorous reaction against the sentiment of the song.

"Oyster Stew," sung by Mrs. Ruth Clements, Holt, Tuscaloosa County, 1952.

A man happened to an accident upon a railroad train,
A-trying to ride and would not pay his fee.
The doctors they consulted, examined him, and said:
"We'll have to saw his leg off at the knee."
They tried to give him chloroform but he wouldn't take the stuff,
Said, "Go ahead while I'm brave and strong.
And while you're sawing off the leg, oh, please, sir, let me sing."
They did, and then he started up this song:

CHORUS: Just tell them that you saw me and I was losing flesh,
To ups and downs will always be a slave.
Just whisper to mother dear if you get a chance,
Her darling boy has one foot in the grave.

I went to a church festival about three weeks ago,
Was just because I had nothing else to do.
Of course I stayed for supper, which was fifty cents a chair.
The waiter brought me in some oyster stew.
I dipped my spoon into the stuff and found it was all milk.
I swore I'd never go there any more.
At last one lonely oyster came strolling up the top.
He looked me in the face and bravely said:

CHORUS: Just tell them that you saw me and I was in the soup.
I've been brought here just sixteen times alone.
Please, mister, don't you eat me; I'm the only one they have.
Remember you have children all your own.
