Spaw,

You are a true wordsmith and worthy of high praise for an interpretation that is probably every bit as accurate as most of those before it and after it.

Several interpreters with obvious Scottish credentials have said categorically it is head or heid and so be it. Nuff said.

Except to say that I now also have a vision of wench rubbing butter on a dandy's scalded tallywhacker (cheers Sinsull) to contend with when singing what was my favourite song.

Thanks for the giggles. Laughter is the best medicine.
