Shanker Jaikishen were the Real Kings of Music. Raju Bharatan, wrote once "Always in their own style" and they befitted the qualification. They created Music rather than Composing it. `Jaan Pehchan ho' sung by Mohammed Rafi from their 1965 movie `Gumnam, was included recently in 2005 (after 40 years of its composition) in the opening scenes of the Holy-wood movie `Ghost World . Hollywood movie The Guru starring Utpal Dutta too included a Shanker Jaikishen's song from "Sasural". The english version of "Baharon Phool Barsaao" sung by Rafi only was also very popular and used in Hollywood album.
