With that post by Stringy I can agree.

I thoroughly enjoy good unaccompanied folk song - and both My Guru and CS are prime examples of modern revelators or interpreters of solo folk song without instrumental accompaniment. Both of them however have impeccable pitch, and one of the first things to put me off about solo unaccompanied singing is poor relative pitch.

I'm not so bothered about vocal harmony drifting up or down over a song so long as the parts are in with each other, but it is still very undesirable and I will re-arrange a song up and down keys until it gets to the one where drift is least. Bad for melodeon players!

Song delivery fashions do however move on, and I like to add guitar and mandolin and percussion accompaniment. More shortly.
