Arthur Smith, a country musician known for the hit “Guitar Boogie” and for “Feuding Banjos,” a bluegrass tune that became “Dueling Banjos” in the film “Deliverance,” died on Thursday at his home in Charlotte, N.C. He was 93... [A] version of “Dueling Banjos” appeared as a deceptively amiable musical duel in “Deliverance,” the 1972 film starring Jon Voight and Burt Reynolds. Mr. Smith was not credited as the writer and filed suit against Warner Brothers after a version of the song reached No. 2 on the Billboard pop chart in 1973. The studio offered a $15,000 settlement but Mr. Smith wanted to go to trial. The judge ruled in his favor. “He recouped all past royalties and all future royalties, and the credit was changed” to show he had written the song.
