Sorry 'bout that

No problem Jim, each to their own.

I'm disappointed you find their accompaniments intrusive. In Fred Jordan's obituary, a certain Mr Karl Dallas says:

True, he sang unaccompanied, regarded as a sine qua non, mostly quite wrongly, by many students of the English traditions, which in their moribundity have for the most part lost touch with the sort of instrumental virtuosity which distinguishes the folk arts in most other parts of the world.

It would be interesting to know in how many other countries, with a folk song tradition, is singing performed solo and unaccompanied.
