A Facebook post from the American Folklife Center at the Library of Congress yesterday has this:

"Being on the twenty-third of June
As I sat weaving all at me loom
I heard a thrush singing in yon bush
And the song he sang was the jug of punch..."

In AFC's 2008 Rediscover Northern Ireland Series, Maurice Leyden sang and discussed the above song. See a video at the link (and read the transcript!):

As Leyden points out in his lecture, June 23 should have been a holiday for the weaver:

"The 23rd and 24th of June for us actually is the feast day of St. John the Baptist, so it would have been a holiday, so the weaver should have been out celebrating, but he's not, he's on his loom.

The feast itself was known because even around 1750, as Kevin Donaher writes, bonfires and drinking were the two features of the day, 'Round the fire young and old, there was much fun and music. A dance started, and games were played.' Or, another man [later] recorded, he said, 'I often heard songs sung there and concertina music, or more rarely the local fiddler would be coaxed out to the fire.'"

The picture is a detail from a larger hand-colored engraving showing Irish weavers at work in the 1790s. See the full image at the second link:

The video of the lecture/performance from Maurice Leyden has this title & description:

Rediscover Northern Ireland 2008: I Am a Wee Weaver: Weaving and Singing in Northern Ireland

Handloom weaving was dominated by men in 19th century Ireland. The Industrial Revolution changed that, enabling women to take the dominant role in the factory production of linen. In this talk, Maurice Leyden discusses the reasons for this historical shift, and the impact of this change on the traditions of singing and songwriting among weavers. To illustrate his lecture, Leyden sings songs composed by linen weavers between the 18th and 20th centuries, setting the songs in their historical context and discussing folklore and customs associated with the weavers.
