Jimmy Carter - with the band since its foundation in 1939 - had the energy of someone a fifth his age, and a voice like gravel in a cement mixer.
Receiving their fourth Grammy, Carter once said that:
"We've been together for six decades but we're still going strong. We're going to continue until God says it's enough."
I sure hope the Good Lord gives them another decade or two before time's up. Hallelujah!
