Ska Punk band from England started in 1994, they have had few line up changes, except for their bassist. They started out small time, but as the band gained popularity they made it a full time concern. A good description of how they started is given in the cover titled song on "This is the Story so far.." They now have four albums and have a large fan base.
They are one of the ska bands who use few horns, and a lot of up picking, while songs do contain horns, there are none in many of the songs, and no horn players are a constant member of the band.
They are this first band to modify the words to "No Woman, No Cry", or any Bob Marley song for that matter, with the permission of his family behind them, because the family liked their cover.
