After launching the teaser of his upcoming film "PK" in Mumbai, Rajkumar Hirani has decided to launch its first song in Delhi, where the movie has been extensively shot.

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

The song is a dedication from Sanjay Dutt to Aamir, where he calls Aamir 'Tharki chokra". It has a very Rajasthani feel to it and 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 Hirani, Aamir and actress Anushka Sharma.
