Having trained in Kathak for the last three years at Nateshwar Nritya Kala Mandir under the guidance of Rajendra Chaturvedi, Kangana shot for the song - composed by Uttam Singh and choreographed by Ganesh Acharya - like a pro.
"Kangana has always been known as a powerhouse performer but now you will see her with new perspective," said Ganesh.
"I was thrilled to see her dedication and the end result. It will be the best performance of Kangana's life."
Clarifying that the song cannot be termed as an item number, Kangana said, "Item numbers are not my cup of tea and mujra songs in Rajjo can't be called item numbers."
"They are highly authentic and a tribute to Gopi Krishna and I enjoyed every bit of dancing that I am getting to do in this film."
All praise for Kangana, "For Rajjo's role, I was looking for a brilliant actress who has been trained in Kathak and Kangana fit into this role perfectly," said director Vishwas Patil.
"I was searching for a powerhouse performer with a regal appeal on the lines of the iconic Vyjayantimala, Wahida Raheman and Madhubala and without any complaints Kangana fulfilled my all expectations."
Produced by Four Pillars Entertainment, Vishwas Patil's Rajjo, also starring National Award winners Prakash Raj and Mahesh Manjrekar and newcomer Paras Arora, is scheduled to release this year.
