Robbie Williams, a self-proclaimed casualty of the British boy-blitz Take That, scuffed his squeaky-clean image by rabble-rousing with Britpop troublemakers Oasis and reemerged as a part-James Bond, part-Frank Sinatra renaissance pop star. A little fast-living combined with his vocal charm, Williams's U.S. debut, The Ego Has Landed, offers a collection of cheeky, inescapably loveable songs served up with a nudge, a wink, and a pinch on the bum.
