Carl, as I wrote to you, the author or first line of Lawr ar Lan y Mor may help to find it. Meanwhile, here is Sospan Fach as I have I have it. I have been told that there are many versions and other verses to this song. Others may have those.

Mary Ann has hurt her finger
David the servant is unwell;
The baby in the crib is crying
and the cat has scratched Johnny bach.

Little saucepan boiling on the fire,
little saucepan boiling on the fire,
and the cat has scratched Johnny bach

Mary Ann's sore finger is better
David the servant is in his grave;
the baby in the crib is now quiet
and the cat is resting in peace.

Little saucepan boiling on the fire,
little saucepan boiling on the fire,
and the cat has scratched Johnny bach.

As I said, there are other versions but that is one. Hazel
