Scottish ones:

Merry hae I been teethin a heckle

There are quite a few Csango Hungarian ones. I've seen some of them done as a re-enactment by women hand-spinners in Moldavia who had earlier in life done flax processing as a real part of the village economy. Their songs were about as bawdy as the ones Burns found. Shredding flax is a pretty dull activity and needs all the livening up you can bring to it. If you're interested, let me know and I can dig out my CDs of this.
