@edgarblythe,
I saw that bit about Billy Bob Thornton. Sorta reminds me of Joaquin Phoneix's abrupt change. Frankly, I think there may be more than meets the eyes behind actors turned musicians.
I sang all the songs connected with the branches of the military because we played at so many veterans hospitals and gatherings.
Here's a bit of history about The Navy Hymn and The Marines hymn that is fascinating to me.
First, The Navy Hymn.
The original hymn was written by William Whiting of Winchester, England, in 1860. It was originally intended as a poem for a student of his, who was about to travel to the United States. In 1861, John B. Dykes, an Anglican clergyman, composed the tune "Melita" for this hymn. "Melita" is an archaic term for Malta, an ancient seafaring nation and the site of a shipwreck involving the Apostle Paul mentioned in Acts of the Apostles (chapters 27-28).
Now the Marines Hymn.
The "Marines' Hymn" is the official hymn of the United States Marine Corps. It is the oldest official song in the United States military.[1] The song has an obscure origin"the words date from the 19th century, but no one knows the author. The music is from the Gendarmes' Duet from the opera Geneviève de Brabant by Jacques Offenbach, which debuted in Paris in 1859. The Marine Corps secured a copyright on the song on August 19, 1919, but it is now in the public domain.
The initial verse is "From the Halls of Montezuma to the Shores of Tripoli." "Montezuma" refers to the Battle of Chapultepec, more commonly known as the battle which took place during the Mexican-American War; "Tripoli" refers to the First Barbary War and the Battle of Derne.
The "Marines' Hymn" is typically sung at the position of attention as a gesture of respect. However, the third verse is also used as a toast during events important to the Corps such as the Marine Corps birthday, promotions, and retirements. Note the line "Here's health to you and to our Corps."
Be sure you check out Brian Setzer's song. It's great.
