Hello. I think the rude version one that everybody is thinking about is from the R Certificate Songbook 1969 as I have just bought the album.

So we'll drink, drink, drink to Lydia Pinkham, savior of the human race.

So they rubbed and rubbed and rubbed her with vegetable compound and now they milk her with the cows.
