"Semper Paratus" (Latin for "Always Ready") is the official song and march of the United States Coast Guard.
The precise origin of the phrase is obscure, although the U.S. Coast Guard Historian's Office notes the first use was by the New Orleans Bee newspaper in 1836, in reference to the actions of the U.S. Revenue Cutter Service during the Ingham incident.
[2] The original lyrics (seen below) were written by Captain Francis Saltus Van Boskerck in 1922, at the cabin of USCGC Yamacraw in Savannah, Georgia; he wrote the music in 1927, on a "beat-up old piano" in Unalaska, Alaska.
[2][3][4] During the run of A Girl in Every Port (1928 film) at the Fox Theater in Washington D.C., a detachment of 50 Coast Guard officers appeared at the theater for the debut of "Semper Paratus", the official song of the U.S. Coast Guard.
The current verse, as well as a second chorus, were written by Homer Smith, 3rd Naval District Coast Guard quartet; Chief Cole; and Lieutenant Walton Butterfield in 1943.
