In 1977, the two joined forced for a memorable performance on the Opry stage. It all starts off by Burnett's observation that "no one picks like a Nashville picker picks," and tries to build up the courage to pluck out a few notes on the banjo. After the pair poke a little fun at each other, they eventually create a spirited ode to the Music City's talented pool of musicians.
The duo even takes a moment to bring an adorable young boy named Louis on stage to show off his strumming skills. I won't spoil the rest of the video for you, but the end of the performance turns into a moment that could only happen at the Grand Ole Opry.
