Looking like a million dollars herself — and rocking an outfit that resembles a traditional Walmart uniform, just with some more pizazz —  Dolly sang a number of her classic tunes … including arguably her most popular tune, “9 to 5” … which she clearly nailed — as seen in the video!

In addition to dipping into her own funds to help those devastated by the hurricane — which has so far killed more than 220 people — her Dollywood amusement park added an additional $1 million to the relief fund.
