Copying the capo on the guitar with one on the banjo gives the game away. It CAN'T be spontaneous. "Deliverance" is not one of my favorite flicks. The "grunt like a pig" part just soured me on the whole movie. Call me squeamish, fine by me.
But you still liked the Banjo Right?
When did it become a sin to practice before performance? It is a movie, a work of fiction.
Your creating standards that simply don't exist. Then condemning a performance because they practiced to create the performance.
I can't claim to know much about Guitar or banjo. But my ear tells me this performance was very professional.
And that I feel was the point. A boy with obvious disabilities also had a remarkable ability.
and what the hell is wrong with grunting like a pig while being raped by your tour guide.? ":O}
