There is a Prom every night (i.e. every evening) for two months during the summer. The last concert is called the “Last Night of the Proms”. It is very famous and millions of people can watch it on television in lots of countries all over the world. Some people who go to the Last Night dress up in funny clothes and wave flags. They hear a piece of music called "Fantasia on British Sea Songs", written by Henry Wood in 1905. It is based on sailors' sea shanties including a 'hornpipe'. The dance that gets faster and faster and the audience clap along, trying to keep up with the orchestra. It includes the song “Rule Britannia”. The orchestra always play Edward Elgar's "Pomp and Circumstance March no 1" which has the tune "Land of Hope and Glory". The concert finishes with Parry's hymn "Jerusalem". The conductor also makes a speech.
