"I am glad that the film's music has really been appreciated and we wanted to celebrate that. We are trying to get all the singers to come and sing. I too would be singing, " Pankaj said in a press statement.
The actor-turned-director has been testing his vocal chords since a few days to be able to sing live, according to a source close to him. Pankaj will sing 'Saj dhaj ke...', which he has sung with Mika Singh, in the film.
"Mausam" is a love story featuring Shahid Kapoor and Sonam Kapoor and it is releasing Sep 16.
Singers like Rahat Fateh Ali Khan, Tochi Raina and Hard Kaur too will perform live at the success party, which is expected to be organised soon.
"Pankaj-ji loves music and has a lot of knowledge of Punjabi folk songs. He gave a lot of valuable inputs to the music of the film. He keeps singing in front of his friends, but has never sung live in front of a huge gathering. He is very excited to perform live in front of the entire star cast of the film, especially son Shahid, and wife Supriya, " said the source.
