I found out (belatedly) that Christian singer/songwriter/guitarist Roby Duke passed away quite a while back.
We graduated from the same school in Mississippi.
This is Roby doing an incredible arrangement of "Be Thou My Vision". Fast forward to the 2:50 mark, as all that precedes it is just Roby noodling around. Enjoy. The last ten seconds are priceless.
Roby was a good man, and he'll be missed.
