This old-timing Boston band, now on their eighth album, inspire devotion extreme enough to make viable a promotional Instagram project of fans' band logo tattoos. It's a bit unfathomable that so many are willing to brand their own flesh in homage; this is to punk as eye patches and toy parrots are to Somali pirates – a hearty but slightly absurd cartoon of the original. But perhaps rabble-rousing reels, big, dumb, bruising guitars and flag-waving, roared choruses of bromidic triumphalism ("We'll live to fight another day/things don't always go our way") just make more sense after several pints of Guinness.
