This is quite a hit Hindi song right now (http://www.moviewalah.com/music/jab-we-m et-2007), from the film Jab We Met (*ing Shahid Kapoor, Kareena Kapur). The director of the film is Imtiaz Ali, who has earlier made Socha Na Tha, and both films are quite refreshingly done despite having the usual rich boy- meets-poor girl (or vice versa) story. The point of interest to us is that this song, Mauja Re Mauja, has snatches of the age-old Assamese folk poem "Rodali e Rod de" as the background vocals at the start, middle and end (not the first line, but the next three lines " Ali Kati Jali Dim, Bor Pira Pari Dim, Tate Bohi Bohi Rod De").
I think this is the first time a mainstream Bollywood film has made such an attempt with Assamese (Mani Ratnam's Dil Se, music A R Rahman, had Zubeen Garg's Xokhi Xokhi Bidexi as part of the background score, but not as part of a song. That film also had a few dialogues in Assamese, which was gibberish for outside viewers as they did not have subtitles, just like the Malayalam lines in the song "Jia Jale" in it were gibberish for us). Dhrubajyoti Phukan, a highly-talented music director and arranger (husband of popular singer Sashwati Phukan) has arranged the music for the film, and apparently it is he who innovatively used the lines in the song. (the music of the movie is by Pritam, who scored the music also for Zubeen's megahit Ya Ali from the film Gangster sometime back). Utpal Borpujari / New Delhi
