Corina performs "Knocking on Heaven's Door" on a harp for her semi-final performance. Piers and Hasselhoff like the performance mainly because she's beautiful.
Hoopalicious dances with hula hoops. She's not hula hooping like normal people do because her movements are more like dance - fluid and graceful - without seeming like she's moving a hula hoop. Yet, somehow the hula hoops keep moving.
