Yes, Stan's version began with the censors objecting to lyrics like "Old man" (derogatory to the elderly), "He don't plant ... " (setting an example of bad grammar for the young), and "get a little drunk ..." (also setting a bad example for the kiddies) and ended up with such gems as

"Elderly man river, that elderly man river,
He mus' .. must know somethin' ... something,
But he don't ... er ... doesn't say nothin' ... er ... anything.
He jes' ... just keeps rollin' ... rolling, he keeps on rolling along.

He doesn't plant taters ... potatoes,
He doesn't plant cotten ... cotting,
And them ... those that plants ... plant them
Is... are ... soon forgotting ...

LOL
