Mayberry's Ladies League is holding its annual concert and they're conducting auditions before the big event. When local farmer Rafe Hollister makes a delivery to the courthouse, he hears Barney practicing and asks what's going on. After Andy tells him about the competition, Barney starts gloating how he's got the audition wrapped up because of how much he's been practicing. At this, Rafe tells them that he's got a pretty good singing voice too, and asks if anybody can audition. He then invites himself to the audition, and much to Barney and Mayor Stoner's dismay, is chosen to represent the town at the concert.
