It's unfortunate that Carl Sandburg removed this song when paring down his The American Songbag. In the introduction to the 1990 reprint, Garrison Keillor gives the last four lines of the chorus:

"Some people like rhododendrons
And some forget-me-nots
But what I like best is the dish of ka-beef
with cabaghes, cabeans, and carotts."

Seems the penultimate line is missing from the above.
