oldhippie, I think it's the same song or similar. The only lyrics I could find online were:

There were plums and prunes and cherries
there were raisins and currants and cinnamon too,
there were nuts and cloves and berries
but the crust it was stuck on with glue.
There were caraway seeds in abundance
it would give yer a fine stomach-ache.
`twould kill any man twice to be eatin` a slice
of Missus Hooligan`s Christmas cake!

Which seems pretty similar to Miss Fogarty's recipe. Wonder which came first?
