We get "Song of The Mountains" at 6 pm on  Saturdays in my area of
southeastern Va. and northeastern N.C.  (PBS station)  I've been
watching the show when I can.  Roni Stoneman was on 2 weeks ago.  I
missed one week, and then the Malpass Family, etc was on this past
Saturday.  It looks to me like they are broadcasting this in order.  
That means Larry and Teresa will be on the 21st.  I'll be out of town
then.

Maybe someone else can check it out!
