This narrative song is a re-telling of the story of David and Goliath from 1 Samuel: 17. It describes the wonder of the crowd, marveling first at what they regard as the impunity; and later at the bravery of David as he kills the Philistine giant. Edwards's setting employs both rhythmic and harmonic choral ostinati and intersperses David's calm reasoned statements with the mutterings and exclamations from the crows as they observe the scene.
The Revival March may not sound familiar to you but dont be alone. John Philip Sousa wrote it in 1876 probably at the tender age of 21 (he was born on Monday 6 November 1854 in Washington D. C.). Even at this point in his life about 4 years prior to his being appointed the 17th Director of the United States Marine Band Sousas writing style was already established. He also had traces of savvy for what the audiences wanted to hear for he used the hymn In the Sweet By and By as the melody for the trio (he did a similar trick later in his life when he used Onward Christian Soldiers written by his good friend Sir Arthur Seymour Sullivan of Gilbert and Sullivan fame as the melody of the trio for his march Power and Glory).
