I for one am not a great lover of unaccompanied singing. The odd one is ok .. but after that it gets boring and I have to go to the bar. If you go back hundreds of years minstrals used lutes etc to enhance the song and make it more pleasurable to the listener before that it was the harp. Over the years the instrument used has changed as different things evolved, but the truth is that most songs are better with some accompanyment. There will always be exceptions .. Stan Rogers' North West Passage for example... but for the most part I can't listen to finger in the ear "sheepwarbling" as my daughter calls it.
