Every Sunday (sometimes incorrectly listed as Every Sunday Afternoon or Opera vs. Jazz) is a 1936 American musical short film about two adolescent girls and their efforts to save a public concert series, which was being threatened by poor attendance.
Small town friends Edna (Deanna Durbin) and Judy (Judy Garland) are upset. Edna's grandfather and his orchestra, who play free Sunday concerts at a local park, have been fired by the town council because the concerts are poorly attended. The girls hit upon the idea of singing at the concerts and set about promoting the next concert. The following Sunday Edna and Judy join Granddad on the bandstand. Edna's operatic style and Judy's swing bring crowds running from all over the park. The event is a huge success and Granddad's concerts are saved.
