Dueling Banjos from the film 'Deliverance'
From Wiki: Widely acclaimed as a landmark picture, the film is noted for the memorable music scene near the beginning that sets the tone for what lies ahead: a trip into unknown and potentially dangerous territory.
In the scene, set at a rural gas station, character Drew Ballinger plays the instrumental "Dueling Banjos" on his guitar with a hillbilly youth named Lonnie (implied as being an inbred albino in the novel) who is portrayed by Billy Redden in the film, though a body double actually played the banjo.
The song won the 1974 Grammy Award for Best Country Instrumental Performance. The film was selected by the New York Times as one of "The Best 1,000 Movies Ever Made", while the viewers of Channel 4 in the United Kingdom voted it #45 in a list of "The 100 Greatest Films".
I vaguely remember watching this movie many years ago - it was probably heavily censored in South Africa at the time - but, the Dueling Banjos scene is unforgettable.
