Hmmm.......there are quite a few versions of the same songs out there with "exquisite" lyrics due to the folk process...and I'm talking about traditional material here not interpretations of Show of Hands material or 'Norwegian Wood'.

Going back to an earlier point...isn't it possible the Coppers' mighty tome just might be an impressive prop?
I'm not suggesting people give up their singaround security blankets wholesale...just that perhaps they might derive some satisfaction from learning the odd one or two songs. Using books it;s possible to come up with completely different material every week but is there any really any point to that?
