Mollee and Nathan bring Bollywood back

I could be wrong, but I believe that they originally performed this during the first week of the competition. I would love to watch the video of the first week and the video of this performance back to back to compare. The judges gave Mollee and Nathan a lot of feedback over the weeks that their were growing... I would love to compare to see if I could find definite proof of growth after all of the judges' comments.
