Cysgod dros Gantre'r Gwaelod
A shadow across Cantre'r Gwaelod
Cregyn gleision dan y tywod
Whey shells under the sand

Plisgyn ar ben y dwfr
Shells above the water
Gwymon gwyrdd yn darllen llyfr
Green seaweed reading a book

Nobody realised
We just danced, danced, danced to the midnight trance
I said "Hey stinky, what's the smell?
You stick around and you kiss and tell"
I say "Hey swimmers, watch for sharks
They come and get you coz you glow in the dark"
I said "No chance to catch our breath
This game of chance goes to sudden death" they say
