I may have stumbled across another good resource. http://books.google.com/books?id=g2jSdOR8aUkC&pg=RA1-PA139&lpg=RA1-PA139&dq=Richard+Cox+and+the+Harvesters&source=bl&ots=aZt-SL0jdb&sig=7H7En#v=onepage&q=Richard%20Cox%20and%20the%20Harvesters&f=false.

Reading this thread sent me searching for information on Flatt & Scruggs and the Stanley Brothers television shows on WSAZ in Huntington WV in the early '50's - some of my earliest memories of music on television. The search led me to this book, which has a wealth of information on the radio and television broadcast history of Country, Old Time and Bluegrass music and musicians.

From a reviewer at the Barnes & Noble site:

I then went in search of "Saturday Night Jamboree", which was also a mainstay at our house when I was a little girl. There is only one extant tape (on youtube) of the show that had at least a ten year run, and that was 1960, so fairly late. Even so, when listened to the mix of music their relation to one another was apparent.

I"m so pleased that this thread popped up again. Except for today's posts, it was all from before my time on Mudcat.
