Filmmaker Sajid Khan is set to don the garb of a disc jockey (DJ) at the launch of the disco number of his upcoming film "Himmatwala"

The song "Thank god it's Friday" has actress Sonakshi Sinha shaking a leg to it in retro style in the film. She makes a special appearance in the movie with the song.

Sajid is busy getting the hang of the DJ equipment, as he gears up for the performance at a posh party place in Mumbai Friday. Sonakshi will also do a live act.

"It is a disco song which Sonakshi is doing in 'Himmatwala', for which Sajid decided we should launch it in a popular party place. He immediately called up Sonakshi if she could drop by for a live performance and she readily agreed on a condition that Sajid would be the DJ in the house, " a source said.

"Himmatwala" is a remake of 1983 hit of the same name and features Ajay Devgn and Tamannah in the lead, along with Mahesh Manjrekar and Paresh Rawal. It is set for March 29 release.
