Bappi Lahiri not only composed the music and sang songs for this film but also had top billing as an actor in it.
The title of this film appears to be a combination of two Hindi film song titles - "It's Rocking" ("Kya Love Story Hai", 2007) and "Dard-E-Disco" ("Om Shanti Om", 2007).[1][2]
Song
Yaad Aa Raha Hai Dard-E-Disco - The tune of the opening of this Bappi Lahiri song was taken from another hit song by the music director from the film "Disco Dancer" (1982). While the original song was written by lyricist Anjaan, the lyrics of this song were written as a tribute to him by his son Sameer.[3]
