("Crack On, Have A Booze!" Das 2013er Hard Skin-Studioalbum erscheint, neun Jahre nach dem Vorgänger "Same meat, different gravy", gleich mit zwei verschiedenen Titeln in zwei verschiedenen Versionen: Als "männliche" Version, "On The Balls" betitelt, mit himmelblauem Cover und Herren-Gesang sowie als "weibliche" Version, "Why Do Birds Suddenly Appear" betitelt, mit altrosa Cover und Damen-Gesang. "12 instant anthems about council estates, sausages, the kids, cunts, the filth and gipsy hill". Der Humor scheint ungebrochen, auch musikalisch ist alles beim alten geblieben: Beste UK Singalong Anthems, immer dicht am Original (Sham 69 meets Cockney Rejects).
