Watch: Katy Perry Covers A Janet Jackson Hit

Leave it up to Katy Perry to have a dynamic opening night of her Witness Tour. You can start watching at the 2:30 mark to see how she transitioned into a classic Janet Jackson song "What Have You Done For Me Lately". It was a great way to end her hit song 'Bon App├ętit'. Katy Perry always has the stage presence, stage production, and of course the lights, the camera and the action to draw you into her animated persona.
