Sinha, who is at odds with BJP after being sidelined in recent the Bihar Assembly elections, told PTI that he would also invite RJD president Lalu Prasad for the book launch.
Asked if leaders of his own party would be called for the book launch function in Patna, he quipped, "It concerns Art and Culture and not Agriculture. Only those who deserve would be invited for the function."
The book, "Anything but Khamosh", written by a Mumbai based journalist, was first released in Delhi by Sinha's "friend, philosopher and guide" and senior BJP leader L K Advani last month.
Sources close to the actor-turned-BJP leader who were present with him at the time of the meeting said Kumar showed a lot of warmth and acted as a perfect host by coming out and seeing off the BJP MP in his car.
