I'm not sure if this is so old that no one cares but the first lyrics shown are very close to Ifca's Castle.
We used to sing it in choir in High School in the late '40s
As I recall it was something like this:
Across the plains of gold and green, a young boy plainly can be seen.
But no tis not a boy at all, it's Ifca's Castle, spires so tall ----
Sorry that is all I can remember.
