Oh no! Our attempt to infiltrate the earthlings' psyches has been thwarted! -Zoot (from Mars)
The Australian version of "Row Your Boat" is called "Kookaburra Sits" - a little longer than "Row" but the melody is similar, and it's the best known Australian round.
Kookaburra sits in the old gum tree Merry merry king of the bush is he Laugh kookaburra laugh kookaburra Gay your life must be.
I am seeing two dear friends tonight who store all kinds of musical miscellany in their brains, so I will ask about "Row".
