The members of "The Bluesmen" who perform in the closing scene are Andy Griffith, Brownie McGhee, Joe Seneca and Ray Templin.
Joe Seneca was born as Joel McGhee, Jr. in Cleveland, Ohio in 1919. Brownie McGhee was born in Knoxville, Tennessee in 1915. Both men died in 1996. Interestingly, the two are not related. Popular thought is that Joe Seneca changed his name to avoid confusion regarding his friend and fellow musician.
