Music : Laxmikant-Pyarelal
Lyrics : Anand Bakshi

What I have used is a Karaoke and NOT the original song. It is a tutorial for upcoming singers to learn from. Besides, this type of karaoke are available in YouTube in millions. Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use.
My video is in no way related to some original song. In support of my statement, I am furnishing you the original karaoke which I have modified.
