I think The old Swan Band do a 48 bar version of "The Oyster Girl"called a"basquet of Oysters"
That's the one you posted the ABC for a few messages back!

"Basquet" has the B music of the Oyster Girl as its B music, with a different A and C.

But the other 48 bar Oyster Girl is the usual Oyster Girl A and B with a C music that I suspect (as does Marje, apparently) comes from somewhere else, tacked on the end.
