I think the line "Jimmie Crack Corn and I don't care" is a mistake.

So many times I hear "LADETTES" staggering out of pubs and clubs totally legless, and the usual anthem is :-

"gimme one glass of champagne and I'm anybody's"

The equivalent line in this song is :-

"Gimme crack corn and I don't care"

not Jimmie Crack Corn which is meaningless.
