Can someone help me transcribe the lyrics to a Welsh song sung in English by Joan Mills?
The link to the audio is here (timestamped): https://youtu.be/iYZFiCZAbJs?t=2133

Here's what I've got so far:

Can Y Melinydd (The Miller Song)
As sung by Joan Mills

I have a golden pony
The fleetest ever seen
Whose light feet to [?], love
Whose shoes [of?] silver sheen

CHORUS
Fal di ral lal di ridey ro
Fal di ral lal di ridey ro
Fal di ral di ridey ro

Twelve pullets and a cockerel
A score of [?]
And fatter pigs than any
Were never pigs like mine[?]

Off goes my flying filly
And flashing silver shone
All rivers, fields, and mountains
To bring you back the moon[?]

I'll travel through the valleys
I'll travel through the hills
I'll travel through the forests
I'll go where'er you will
