Bon Jovi fans are deemed some of the most loyal in rock.

Little wonder that when Bon Jovi announced “What About Now,” his 12th studio album, and launched a world tour, fan board posts surged. Not that frontman Jon Bon Jovi hasn’t been in the spotlight quite a bit anyway. His recent high-profile appearances included a Dec. 12 appearance at a Superstorm Sandy relief event that included Paul McCartney, the Who, Bruce Springsteen and others.
