I think this is getting a bit out of hand. We were talking about Peter's singing style.
My views on Peter's are on the Wikipedia article about him if anyone is interested. He was a man I respected and trusted. My wife will not have a word said against him, after he fed her and helped her for three days when she lost all her money at a Folk Festival, while I was working abroad.
Brian's post sums up his singing style very well. I am sure he had a lot more to offer when he left us. So let's concentrate on his legacy. I hear echoes of his singing and playing in lots of the younger singers, and it always brings a smile.
