 Betty and Wilma complained to their husbands that they want to go on a date more often. To compensate, Fred and Barney brings them to the amusement park. During a break, Fred records a song in a "recording box" and forgets the record when Wilma picks him up. A teenager picks up the record and after listening, swear they have found a new "idol". After the record company broadcasts the song on the radio, Wilma calls them to tell it is Fred. A manager takes Fred on a concert tour, under the "stage name" of Hi-Fye!
