Don't know if this is relevent or not, but the original version that Don and Arthur did on the "Arthur Smith Show" was with tenor and five string.

Totally off track, but boy would I have loved to have been around (and in the vicinity) when those old morning (6am) radio and TV shows were done. I have always hated to get up early...but to have seen Flatt and Scruggs, The Stanleys, Reno and Smiley, The Wilburns etc. Heaven
