The main reason is to avoid the risk of my performance being pirated on the internet. 
I appreciate the suggestion though @mikeellwood . 
It will, on the other hand, be quite hard to stop me singing it at the next party, especially after a gwydred neu ddau.

OK, me again!
When I clicked on an on-line Geiriadur for another reason, as if by cookie magic, it came up with:
Sgram (the food variety) for quick bite and and sgramio for quickly gobbling up food or something similar.
It showed sgram as a loan word from “scran”: Eng Ar. I assume that is archaic English, but that it has been in the Welsh Language since the 19th Century.
