I'm to blame! I started the thread!
I'd like to make two comments here.
If Shirley had got up at my local folk club - back in the day - and I hadn't known who she was, I wouldn't have been impressed!
I wouldn't have gone home I told my wife that I'd just heard a wonderful, inspiring - whatever - rendition of a folk
Secondly, I wouldn't dream of playing a track by Shirley, to a non-folky friend - as an example of great - even good - folk singing.
On one level it could be called a "personal thing" but if the folk scene had been full of Shirley Collin's type singers when I first got in to folk music in the 60s, then I wouldn't be here now writing this!
