Did the CFL invite Albertans Jann Arden and Nickelback to play the Grey Cup to please HMH (His Majesty Harper)?

It seems like Harper worms his way into almost any situation with which he is involved so that his cronies and compatriots reap the awards of his place of privilege. I suppose it could be coincidence that two Albertan acts entertained at a Grey Cup located in BC but since when has anything occurred concerning the PMO that wasn’t pre-rigged by HMH himself?
