Will Justin Bieber's performance at halftime add any new CFL fans?Saturday's announcement that this year's Grey Cup halftime show will feature Justin Bieber (as well as the less-controversial Carly Rae Jepsen, Gordon Lightfoot and Marianas Trench) has already sparked plenty of interesting reactions, from Elliotte Friedman's "Rogers Centre to overflow with ear blood" to enthusiastic people plotting out potential set lists. Leaving aside the debate over the musical abilities of Bieber, though, what's interesting is that for the second year in a row (hello, Nickelback!), the CFL has gone with an act that's both extremely popular with groups outside the league's primary fan demographics and reviled by many inside those demographics. Of course, this year they've dialed that down by having Bieber share the stage with Jepsen, Lightfoot and Marianas Trench, so there's probably something just about everyone can at least tolerate here. That raises its own questions of if trying to hit every box is the right strategy, though. Expanding the league's fan base is certainly a laudable goal, but is this approach going to do it?
