The Crue is BACK!  Hair metal gods Motley Crue held a press conference in Los Angeles yesterday to announce their summer tour, Crue Fest.  This 41-city venture will operate similarly to Ozzfest with several bands touring together, who, according to bassist Nikki Sixx , "live the rock and roll lifestyle."  The tour will be headlined by Papa Roach, Buckcherry, Sixx:AM and Trapt and of course The Crue themselves who are releasing a new album, Saints of Los Angeles in June.  Get out your Aqua Net and spandex kids, it’s time…
