For He's a Jolly Good Fellow

"For He's a Jolly Good Fellow" is a popular song that is sung to congratulate a person on a significant event, such as a promotion, a birthday, a wedding (or playing a major part in a wedding), a retirement, a wedding anniversary, the birth of a child, or the winning of a championship sporting event. The melody originates from the French song "Malbrough s'en va-t-en guerre" ("Marlborough Has Left for the War").

History
The tune is of French origin and dates at least from the 18th century. Allegedly it was composed the night after the Battle of Malplaquet in 1709. It became a French folk tune and was popularised by Marie Antoinette after she heard one of her maids singing it. The melody became so popular in France that it was used to represent the French defeat in Beethoven's composition Wellington's Victory, Op. 91, written in 1813.

The melody also became widely popular in the United Kingdom. By the mid-19th century it was being sung with the words "For he's a jolly good fellow", often at all-male social gatherings, and "For she's a jolly good fellow", often at all-female social gatherings. By 1862, it was already familiar in the United States.

The British and the American versions of the lyrics differ. "And so say all of us" is typically British, while "which nobody can deny" is regarded as the American version, but the latter has been used by non-American writers, including Charles Dickens in Household Words, Hugh Stowell Brown in Lectures to the Men of Liverpool and James Joyce in Finnegans Wake. (In the short story "The Dead" from Dubliners, Joyce has a version that goes, "For they are jolly gay fellows..." with a refrain between verses of "Unless he tells a lie".) The 1935 American film Ruggles of Red Gap, set in rural Washington State, ends with repeated choruses of the song, with the two variations sung alternately.

Text
As with many songs that use gender-specific pronouns, the song can be altered to match with the gender of the intended recipient. If the song is being sung to two or more people, it is altered to use plurals.

British version
For he's a jolly good fellow, for he's a jolly good fellow For he's a jolly good fellow, and so say all of us!

American version
For he's a jolly good fellow, for he's a jolly good fellow For he's a jolly good fellow, which nobody can deny!
