Will,

Sorry, I do understand that you are not putting Ralph Rinzler down and I hope I didn't come across as "bristling". I agree with you regarding the so called belief in authenticity but unfortunately there was a lot of crap around at that time regarding what was or wasn't authentic and there still is to some extent. The folk/old time/bluegrass/police are still around fortunately a lot fewer now. Just prior to the Big Folk Scare we had a similar situation here in the jazz world trad versus mod and mouldy fygges and dirty boppers.
As I said earlier I do believe that Ralph's approach with presenting Doc was the way to do it taking into consideration the potential audience of the time.
