I had Kenny Hall on my mind just yesterday. While looking for something else for a Folk Center project, I came across the recording from his appearance in Mountain View in 1978. Definitely timeout from what I was looking for.

Our last concert of the season this year(October 28)will be a dandy with Doc Watson and David Holt. Some of you might even want to start planning a trip to Arkansas for that one.
