Singer Shaan’s son Shubh has marked his debut with his father in a theme song for entertainment company Yash Raj Films. The 11-year-old will be crooning to the track penned by Shaan and composed by band Superbia comprising him, Gourov Dasgupta and Roshin Balu. The video, which has been made by YRF for their web series Sex Chat with Pappu & Papa, showcases moments that boys spend with their fathers. “When Ashish Patil (Head of Y-Films) shared the idea of having an ‘ode to papa’ song in Sex Chat with Pappu & Papa we jumped at the idea. But we were short on time, so I literally wrote the lyrics while we were composing the song. Getting Shubh (my younger son) to sing was pretty convenient,” Shaan said in a statement.
