The reason that this is not a silly conversation is that Pete Seeger's style of banjo playing has not been fully appreciated by the old-time and bluegrass community. The point is not to add to Pete's book but to clarify exactly the contribution he has made to the five-string banjo
through analyzing his techniques in a thorough fashion and showing people how to do it.
There are few people today who have assimilated his method of playing and particularly his ability to accompany a song. This style of playing might be an "endangered species".

Frank Proffit doesn't have Pete's musical sophistication. Actually Pete Steele was an up-picker. "Pay Day at Coal Creek" for example.

I would be interested to see how you applied what information you received from Pete's book.
