Rishi Kapoor, Randhir Kapoor and Sajid Khan are all big fans of RD Burman.

During the lunch breaks on the sets of their film, all three of them would get together and entertain them selves and the rest of the cast and crew by singing all the hit songs of Burman.

Even though RD gave more hits for Rishi's movies, brother Randhir was closer to the composer.
