The producers of Cirkus have released the second song from the movie following the massive success of the chart-topping song, Current Laga Re. The song, Sun Zara, features two different Ranveer Singh personas and is a throwback number right out of the 1960s. In addition to portraying two distinct Ranveers in the song, Jacqueline Fernandez and Pooja Hegde play female lead roles in the movie. Sun Zara is a colourful, upbeat song that was written in an imaginary world. Shreya Ghoshal and Papon perform the Rockstar DSP (Devi Sri Prasad) musical song Sun Zara. The lyrics to the love song were penned by Kumaar. It is anticipated to debut on the big screen on December 23.
