Think of hit Hindi film songs of the late 1960s, 1970s, 1980s and early 1990s that many of us enjoy humming, singing or love listening to, and you will see a lot of them have been composed by Rahul Dev Burman aka RD Burman. He was and still is lovingly known as Pancham Da, the quintessential music composer who ruled the hearts of umpteen Indians with his unique creations.
