When S D Burman walked out after listening to 'Dum maro dum'

Musician Sachin Dev Burman was terribly upset with his son R D Burman's composition in "Hare Rama Hare Krishna" and walked out of the studio when he heard the recording of the song 'Dum maro dum'.
This and several other interesting facts about the legend find mention in a book "S D Burman: The World of His Music" by writer Khagesh Dev Burman.
Published by Rupa and translated to English by the author and S K Ray Chaudhuri, the book has a detailed list of Sachin's songs and analysis of his unique style and music.
Quoting extensively from Sachin's memoir, "Sargamer Nikhad", the author delves into his childhood, things that shaped his character and musical talent, the days of struggle - and the rise of the maestro.

Even though Rahul cut a path of music very different from his father's for himself, he could not escape the influence of his father. Sachin groomed him as a composer and encouraged him to learn to play different instruments, says the author.
He was not hurt with the music of 'Dum maro dum' not because he had to pave the way for his son when Dev Anand, in spite of their long association, ignored him and appointed Rahul as music director "Hare Rama Hare Krishna" but because he thought his son had forsaken him.
"He was dismayed when he heard the recording of the song 'Dum maro dum' in the studio. He was upset; he thought his son who carried his flag, whom he had taught music from childhood, had forsaken him.

"Was it a repudiation of inherited culture? Was it an attempt to disown his father? Rahul saw his father slowly walking out of the studio with his head bowed down. It looked as if a defeated king was retreating from battle," the book says.
