Yep, they did a routine on Jai Maa Kali :) I think it was freestyle but I remember it having classical aspects in it too :)
But irrelevant of whether or not they've done classical or not.. They DO deserve to be in the finals im my opinion anyways.. Outa all the jodis, theyve shown the most improvement. Tbh, at the beginning, I never thought they'd make it this far.. But they have! and thats coz they worked hard and improved considerably.
