At the Florida Folk Festival, Chris, John, and I were picking at our campsite, warming up to play a set. Since John knows a great many of Bill Monroe's tunes and plays them on the banjo, we were exploring the Monroe "deep catalog." We did play 'Jerusalem Ridge', but we also played 'Old Ebeneezer Scrooge' and 'Come Hither to Go Yonder' and 'The Old Mountaineer' and 'Crossing the Cumberlands' and 'Right, Right On' and more.
A person who was new to this kind of music stood by one side and listened. When we finished one tune she asked, "Who wrote that music that you're playing?" I replied, "Bill Monroe." She asked, "Is it authentic?"
I pointed to John and said, "That man right there was playing banjo for Bill when he was writing and playing these tunes, and yes, it's authentic!"
