Ska punk is alive and well. Some of those older ska punk bands are still going (Reel Big Fish, LTJ, Mad Caddies, Streetlight Manifesto etc) but over in the UK there are still a lot of new ska punk bands and the scene is pretty healthy, my favourites are more skacore (yes, that's a thing
) such as King Prawn, Random Hand and Capdown. I don't follow the scene as much as I did 5 years ago but there's a lot of great bands. Tempted to start sending this stuff in roulettes, probably won't fair too well though.
