Brought to my attention last week were these guys - Heavyball. Bit of ska, bit of Mod going on here (at least in the look) and that classic, slightly bouncier 2-toney sound you might have originally associated with the Specials... but slightly happier. They are from Nottingham, but nowadays they can be found kicking around London... like everyone sensible... [here comes the abuse]
They are a bit zany, but then I personally don't think you could pull off the ska style without a bit self-awareness nowadays. Anyway if you want more, go to their site here.
