Singer Sonu Nigam's apology is not enough, he must face repercussions for such harsh words, said Kannada director K Ramnarayan. After the controversy at a concert in Bengaluru where Nigam linked Kannada to the Pahalgam Terror Attack, two songs sung by him in the film 'Kuladalli Keelyavudo' have been replaced with track versions by another singer, Chetan Sosca.
