"We are against (TV) channels who invite Pakistani singers. It is their tactic to create controversies and hence gather more TRPs," said Amey Khopkar, president of Maharashtra Navnirman Chitrapat Karmachari Sena, a group affiliated to the MNS.
"We have written to Colors and Sahara not to air the show. Otherwise we will disrupt their shoot schedules," he added.
Khopkar said he has also written to Asha Bhonsle, who is among those who will participate in the programme alongside Abida Parveen and Runa Laila.
"I have requested her not to be a part of the show as a diva like her is looked upon by many, and hence she should not be sharing stage with Pakistani vocalists," Khopkar said.
"When Pakistan is inflicting injuries on us, why should we entertain Pakistani artistes?" Khopkar asked.
Reacting to the MNS stand, Bhonsle said she was a proud Maharashtrian who believed in the idea of "atithi devo bhava" (a guest is like a god).
"I don't like politics because I don't understand it... But I love Raj Thackeray. In spite of whatever he thinks about me, I still love him. I am a singer and I understand the language of music," Bhonsle said.
