Dueling Banjos (HD)

Same as below except in HD. See comment in the one below.

Deliverance - Banjo Duel

Unlike Ronny Cox with his guitar, actor Billy Redden did not know how to play banjo for the famous "Duelling Banjos" scene. To simulate the realistic chord playing on the banjo, another boy, who was a skilled banjo-player, played the chords with his arm reaching around at Redden's side while Redden picked. On the soundtrack, musicians Eric Weissberg and Steve Mandel are actually playing.
