Brenda Wootton kindly wrote down the lyrics of Jan Knuckey abot 30 years ago (with translations into normal English).

Here the 3rd verse:

Boy Jan he "fetched his cowas" one day, (= "very bravely")
To "speak his mind" to Grace (= "tell her the truth")
But when he got inside the door
He didn't "have the face" (= "he was shy")

Kind regards,

Richard
