From Wikipedia on Light Cavalry Overture:
Light Cavalry Overture is the title of the overture to Franz von Suppé’s operetta Light Cavalry (German: Leichte Kavallerie), premiered in Vienna in 1866. Although the opera is rarely performed or recorded, the overture is one of Suppé's most popular compositions, and has achieved a quite distinct life of its own, divorced from the opera of which it originally formed a part. Many orchestras around the world have the piece in their repertoire, and the main theme of the overture has been quoted numerous times by musicians, cartoons and other media.
