Melissa, I thought of that too! I think we were to some extent on the right track. As a single item, "Ladybug's Picnic" is not what SeaCanary is looking for, but as a GENRE, that's exactly where he or she may find a lot of relevant songs. There are traditional children's counting songs most everywhere...but I'm away from my library at the moment and can't think of British or Celtic ones offhand.

I can think of a rowing shanty from Brittany that goes

Hourra, les filles a dix deniers
Hourra, les filles a dix deniers
a dix deniers, les filles en sont
tirons, mes garcons, sur les avirons,

Hourra, les filles a neuf deniers,
etc.

and then counts down from ten to one.

But I don't know if it's useful, because the chorus isn't mostly numbers, per se. I'm waiting for SeaCanary to respond with some clarification as to what is being sought.
