I was listening to a recording of "Gwenni aeth i ffair Pwllheli", and it felt to me as though it were missing verses. However, I can't for the life of me think what they may be!

The verses in the recording (by Gwenan Gibbard? maybe?) are these:

Gwenni aeth i ffair Pwllheli,
Eisie padell bridd oedd arni,
Rhodd amdani chwech o syllte,
Costie gartre ddwy a dime

Gwenni aeth yn fore i doro,
Gwerth y chweswllt rhwyng ei dwylo,
Rhodd y fuwch un slap â'i chynffon
Nes oedd y chweswllt bron yn deilchion.

Gwenni aeth yn fore i olchi,
Eisie dillad glân oedd arni,
Tra bu Gwen yn nôl y sebon,
Y dillad aeth i lawr yr afon.

Are there actually more verses to this song, or am I just having a brain failure?
