I see that it's been several years since this thread has been posted on, but I'll toss in my two cents anyways. Came looking for lyrics when this tune popped into my mind and I was trying to teach it to my kids but couldn't remember very many words. I learned it at a (very white)Girl Scout camp somewhere in the Northeast sometime in the early 1980's. My recollection says the song went something like:

Hooka tooka my soda cracker?
Does your Mama Chaw tobacca? (Yes she does)
If your mama chaws tobacca,
Then it's hooka tooka my soda cracker

Red and Green oh Rocky Road
I said
Red and Green oh Rocky Road
I said
Red and Green oh Rocky Road
I said
Promenading Green

Now, granted, the song never made any sense to me so I am probably not likely to have remembered it accurately and I make no promises that my recollection of how the song goes is anything like how they sung it at camp. But, interestingly, my mother was a big fan of PP&M and when I came home singing the song it was completely unfamiliar to her or any one else in my suburban neighborhood. I'll have to find a recording and see if my memory of the tune is even accurate. What a fun story, would be very cool to see the history of the song charted on a tree with the lyric and geographic changes plotted over time, like a genetic map. Loved the story about warning the prostitutes. Thanks for the info. - G
