I am 62 and remember this song from my early days at primary school
I may not be 100% accurate, but I remember...
Marianina the fairy maid...

In this land there is a fairy maid
and within it`s beauty she is arrayed
she`s my darling and I love her so
who is she I cannot tell
but I know love her well
who is she I cannot tell
marianina marianina come and turn us
into "Foam"???
