Johnny Crooner, Yemi Alade Performs For General Buhari

I know it is just a matter of "them doing their jobs" but in other countries when artists perform for or during a politician's rally; it is usually their way of endorsing that candidate for their fans and supporters too, I just wonder, with Yemi Alade performing for controversial former head of state of Nigeria and I think to myself surely something is wrong with this, is this not morally questionable?
