Boston Ballet celebrated its successful season-opening performance Thursday with a little soiree at Back Deck restaurant in Downtown Crossing. Joining artistic director Mikko Nissinen were Boston Ballet’s resident choreographer Jorma Elo, executive director Barry Hughson, and principal dancer Jeffrey Cirio. . . . Who better to judge McGreevy’s hot-wing-eating competition than Mark Wahlberg’s buddy Nacho? A self-styled extreme eater who’s been taping a show for Fuel TV, Nacho had no trouble picking the winners Thursday. . . . Live Nation announced Friday that a second Jason Aldean show has been added, on July 12, at Fenway. Tickets for the second show go on sale Nov. 2. Aldean’s first show, July 13, sold out in seven minutes.
