John Stafford Smith - born in Gloucester and Gloucester Cathedral organist from 1743-1782. Very ironically the star-spangled lyrics were written by an American in America - Francis Scott Key - in 1814 who was inspired by a victory over the British in 1812. He nicked the Englishman's / Gloucestrian's melody - though he wasn't the first American to do so.
"On September 14, 1814, U.S. soldiers at Baltimore’s Fort McHenry raised a huge American flag to celebrate a crucial victory over British forces during the War of 1812. The sight of those “broad stripes and bright stars” inspired Francis Scott Key to write a song that eventually became the United States national anthem. Key’s words gave new significance to a national symbol and started a tradition through which generations of Americans have invested the flag with their own meanings and memories".
