The team of the Aamir Khan-starrer is going to be in Delhi on Saturday for the launch of the song, 'Tharki chokro'.

The song is a dedication from Sanjay Dutt to Aamir Khan, where he calls Aamir 'Tharki chokro'. It has a very Rajasthani feel to it and Rajkumar Hirani has roped in talented Rajasthani singer Swaroop Khan to be the voice of the song.

"Raju was keen on launching the music in Delhi as the entire team had a really good time while shooting there," said the film's spokesperson.

The song will be launched in the presence of Rajkumar Hirani, Aamir Khan and Anushka Sharma.
