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.
