Thought I had some notes on WOAD (the song) in my old handwritten notebook. Found the song but no notes as to where, or how, it originated. I sang it almost the sama as Micca's version:

WOAD (Tune: Men of Harlech)

What's the use of wearing braces,
Hats or spats or shoes with laces,
Vests or pants you buy in places,
Down on Brompton Road.
What's the use of shirts of cotton,
Studs that always get forgotten,
These affairs are simply rotten,
Better far is Woad.
   Woad's the stuff to show men,
   Woad to scare your foemen.
   Boil it to a brilliant blue,
   And rub it on your legs and your abdomen.
   Ancient Britons never hit on
   Anything as good as Woad to fit on
   Neck or knees or where you sit on,
   Tailors, you be blowed!

Romans came across the channel,
All dressed up in tin and flannel;
Half a pint of Woad per man'll,
Clothe us more than these.
Saxons you may save your stitches,
Building beds for bugs in britches,
We have Woad to clothe us which is,
Not a nest for fleas.
   Romans keep your armors,
   Saxons your pajamas,
   Hairy coats were made for goats,
   Gorillas, yaks, retriever dogs and llamas.
   March on Snowdon with your Woad on,
   Never mind if you get rained or snowed on,
   Never need a button sewed on,
   Good for us today!

I'd never seen Guest Sally's 3rd verse. It's a hoot and I'll add it to the words in my notebook.
