This London gentlemen's club was dedicated to the ancient Greek poet Anacreon, who wrote some pretty racy stuff back around 500 B.C. The society was made up of amateur musicians, and their club song, To Anacreon in Heav'n, eventually became so popular that other people started writing their own words to the song's music. (Think of it as an early form of sampling.)

One of the songs that borrowed that tune was The Defence of Fort M'Henry-later known as The Star-Spangled Banner.
