Ganesh Acharya says he has choreographed the "Po po po" song in "Son of Sardar" for children.

The promotional song features Ajay Devgn, Sanjay Dutt and Salman Khan in a rare frame. Salman is seen doing a peculiar facial movement.

"When Ajayji told me that we have to do 'Po po po' song, I said I have a side movement in mind. I was very sure that I have to do this song for kids and I did it. So I'm happy that I had thought it to be for kids and successfully did it," Acharya said in an interview.

He is also happy to have got a chance to work with the three actors.

"I don't know whether I'll get this experience again or not. All three stars - Ajay, Salman and Sanjay - are together and all of them have done a great job," he said.

"I am honoured to have worked with all three stars and all of them did what I said and did the song," he added.

Directed by Ashwin Dhir, "Son of Sardar", releasing Nov 13, also features Sonakshi Sinha.
