Black Horse Troop, composed by John Phillip Sousa, performed by Brassman Bart

Hello! This week's number is The Black Horse Troop, written by John Philip Sousa and performed by me, Brassman Bart. I perform all the parts using Audacity 18 track virtual recorder, and all 18 tracks were used in the production of this number. The Black Horse Troop was originally published in 1925 and just became public domain on January 1, 2021. This week's trivia questions are the following: 1. At what age did Sousa first join the Marines? 2. What was his first published composition? 3. How many services did Sousa serve in? Bonus question: How much did Sousa earn in royalties from the march, The Washington Post? Answers will be given at the end of next week's video.
