Joe I have a recording of the song on the Cambridge Crofters' eponymous LP (Barleycorn CR76 Stereo, 1976). The tune is close to that in the DT, and appears to be a version of Mr Mason's.The sleeve notes say:

Farming songs were often associated with the farming year and its jobs. This traditional song from Yorkshire would have been sung by the shepherds at sheep-shearings and the feasts that followed. When wool was England's wealth, the shepherd was highly respected among countrymen. The song is similar in its enthusiasm to the songs of the Copper family in Sussex.

TARRY WOOL

Tarry wool, oh tarry wool,
Tarry wool is ill to spin,
Card it well, oh card it well,
Card it well ere you begin.

When it's carded, wove and spun;
Then your work is nearly done.
But when it's woven, dressed & clean
It'll be a clothing for a Queen.

Up you shepherds run & skip
O'er the hills & valleys trip.
Singing the praise of tarry wool
And in the flock that serves it well.

Poor, harmless creatures without blame
They clothe our back & cramp the whame,
Keep us so warm & hearty, too,
Well on us our tarry wool.

Who'd be a King, can any tell
When this shepherd he lives so well
Lives so well & pays his due
With honest work & tarry wool.

I'd be surprised if this is the only commercial recording from the revival, but it's the only one I've heard. (PS - I must have forgotten the bit about it being from Yorkshire - most of the Cambridge Crofters' stuff was Scottish, and I have assumed for the last 30 years that this was too.)
