In English popular culture, the "traditional" pub songs typified by the Cockney "knees up" mostly come from the classics of the Music Hall, along with numbers from film, the stage and other forms of popular music.
The tradition is continued in the UK by acts such as Chas 'n' Dave, many of whose works are in a 'pub song' format.
The widespread retail release of 28 Irish PubSongs by Canada's Madacy Records label in 1996 (typically for no more than $6 to $7) helped to introduce a whole new generation to the infectious up tempo style the Clancy Brothers introduced.
If you should drop into to a real Irish pub, there is a good chance you would hear many of the songs on this album.
At the same time, while there are "rebel songs" such as "Rising of the Moon", "Foggy Dew", "The Minstrel Boy" and "The Men of the West"; the Clancy Brothers never come across as overtly political as say the Wolfe Tones.
