Here's what I know of the song:

A Maid Going to Comber
Her markets to learn [pronounced 'tae larn']
And to sell for her mammy three hanks of fine yarn.
She met with this young man along the highway
Who caused this young damsel to dally and stray.

chorus -
Come sit ye down by me, I'll do ye no harm,
Sit ye down by me, this new tune to learn,
and here is three guineas your mamy to pay,
Come leave by your yarn till the next market day.

This maid she went home, but the words that he said,
And the song that he sang, it still ran in her head.
She said, "I'll go find him by land or by sea,['say']
Till he learns me the tune called 'The Next Market Day"
