"Columbia, the Gem of the Ocean" is an American patriotic song which was popular in the U.S. during the 19th and early 20th centuries. Composed c. 1843, it was long used as an unofficial national anthem of the United States, in competition with other songs. Under the title "Three Cheers for the Red, White, and Blue," the song is mentioned in Chapter IX of MacKinlay Kantor's Pulitzer Prize-winning novel Andersonville (1955). It was also featured in the 1957 musical The Music Man. In 1969, "Columbia, the Gem of the Ocean" was the music performed by a U.S. Navy Band embarked aboard USS Hornet as one of the ship's helicopters recovered the Apollo 11 astronauts from their capsule named Columbia after a splashdown in the Pacific Ocean.

The Music Man is a musical with book, music, and lyrics by Meredith Willson, based on a story by Willson and Franklin Lacey. The plot concerns con man Harold Hill, who poses as a boys' band organizer and leader and sells band instruments and uniforms to naïve Midwestern townsfolk, promising to train the members of the new band. Harold is no musician, however, and plans to skip town without giving any music lessons. Prim librarian and piano teacher Marian sees through him, but when Harold helps her younger brother overcome his lisp and social awkwardness, Marian begins to fall in love with him. He risks being caught to win her heart.
