A serious note.
I always blamed P K mishra who penned Hindi lyric s for Rahman's music as many Tamil movies got dubbed in Hindi eg Humse hai Muqabala, Love Birds, Hindusthani, Thalapathi, My Brother Nikhil, Saza-e-Kalapani, Duniya Dil Walonk, etc.
But a deeper look into his work made me change my opinion. When given liberty this guy wrote some great lyrics like
Bharat humko jaan se pyara hai
Dil hai chota sa
Many at times he was caught in a situation where he could not do good lyrics because there were n o appropriate words.
Rahman was once asked in an interview how do you feel about lyrics like Rukmini Rukmini (Roja), he said he doesn't understand Hindi lyrics.(......😕)
P K mishra passed away some time back in Chennai.
Peace to him..!
