The 'kid' never actually played the banjo... it was faked in the movie with the help of a real player's left hand from behind him -- much like things are faked in Biden's 'Administration'.... The song is a recording with Eric Weissberg and Steve Mandell playing the banjo and guitar parts... https://en.wikipedia.org/wiki/Eric_Weissberg https://en.wikipedia.org/wiki/Steve_Mandell
Yes, it's a great movie. But, the rape scene might be considered tame, compared to a modern White House kindergarten drag show. I can't wait until the movie gets banned, for 'negative portrayal of gay sexual acts'.
