The Old Barn Dance: A horse trader named Gene Autry (Gene Autry) arrives in Grainville with his horses and outfit prepared to put on a barn dance to attract potential horse buyers to an auction.  The horse trading business has been affected lately by the increased use of tractors to replace horses for farm work.  Radio station owner Sally Dawson (Joan Valerie) approaches Gene and offers him a contract to sing on a program sponsored by Thornton Farming Equipment, the area's leading manufacturer of tractors.  Unconvinced that tractors could ever replace horses, Gene refuses her offer, but is still attracted to her and invites her to his barn dance that night.

The Champs: The Champs were an American rock and roll band, most famous for their Latin-tinged instrumental "Tequila".  The group took their name from the name of Gene Autry's horse, Champion, and was formed by studio executives at Gene Autry's Challenge Records to record a B-side for the Dave Burgess (a.k.a. Dave Dupree) single, "Train to Nowhere".  The intended throwaway track became more famous than its A-side, as "Tequila" went to No. 1 in just three weeks and the band became the first group to go to the top spot with an instrumental that was their first release.  The song was recorded at Gold Star Studios in fall 1957, and in 1959 won the Grammy Award for Best R&B Performance.  It sold over one million copies, and was awarded a gold disc by the RIAA.

Throughout these years, Autry used three horses to portray "Champion": the original Champion who appeared in Autry films from 1935 to 1942, Champion Jr. who appeared in Autry films from 1946 to 1950, and Television Champion, who appeared in Autry's films from 1950 to 1953, and in the television series during the 1950s.  Several other "Champion" horses were used as stunt doubles and for personal appearances throughout the years.
