Veteran actor Mithun Chakraborty, the 'grandmaster' of the Zee TV show, plays a key part in Boss. He essays the role of Akshay's on screen father.
In real life, Akshay has immense respect for Mithun-da, and he even seeks advise from Bollywood's original 'disco dancer' once in a while, said a source.
So, it was a special chance for him to launch a song from the film on a stage which Mithun-da is so closely associated with. Actress Sonakshi Sinha, who will be in a special appearance in the song, will launch the number along with Mithun.
Sung and composed by rapper Yo Yo Honey Singh, Party All Night is touted to be a chartbuster in the coming days.
Boss also stars Shiv Pandit, Aditi Rao Hydari, Danny Denzongpa, Ronit Roy and Johnny Lever. Co-produced by Viacom 18 Motion Pictures, Cape Of Good Films and Ashwin Varde Productions, the film is releasing in October.
