I love this. I sent a link sometime back to a friend so he could hear it. He said it sounded like an elderly local organist who should have had the wisdom to quit playing. :-)

Was is Mozart or Haydn (as did some others, I think) who wrote music that was off-key and had wrong notes in imitation of a clutzy village ensemble?

From the poster of that video: "...the horns alone conclude in the tonic key [of F major]. The lower strings behave as if the tonic has become B-flat, while the violins and violas switch to G major, A major and E-flat major, respectively."
