Of an Irishman who comes to London then is called back home by his sweetheart. Know mostly for the chorus: "It's a long way to Tipperary, It's a long way to go, It's a long way to Tipperary, to the sweetest girl I know. Goodbye, Piccadilly...."
The folklore about this song is, if anything, better than the song itself (which, apart from the tune, is banal). Jack Judge came into a town on New Year's night and claimed he could write a song then and there. Challenged, he wrote "Tipperary."
Harry Williams was (like Judge) a vaudeville performer. The legend says that Judge owed Williams money, and offered this song in payment of the debt.
It is, of course, no longer possible to verify this. What is certain is that the song became immensely popular in the First World War, though more for the chorus (many, many Tommies came from London, after all) than the plot. - RBW
