Actor-politician Sunny Deols son Karan says shooting the song "Hoja awara" for his debut film "Pal Pal Dil Ke Paas" was physically challenging. The song, released on Tuesday, shows Karan and Sahher Bambba's chemistry. The song has been shot in various locales of Himachal Pradesh -- Kaza, Tabo, Spiti Valley and Khyber. It is sung by Ash King and Monali Thakur, and has been penned by Siddharth and Garima.

"We had a great time shooting for the song. During the shoot, we did a variety of adventure sports from rappelling to zip lining to the river crossing. Though it was physically challenging, I thoroughly enjoyed shooting for 'Hoja awara'," Karan said.
