Y-Films has just launched a super cool single of India’s first transgender band – 6 Pack Band called ‘Hum Hain Happy’. The 6 Pack Band consists of six transgender singers hailing from India’s ‘Hijra’ community. It’s an initiative created and driven by Y-Films to help further the cause of gender equality in India. A take on Pharrell WilliamsHappy, this adorable song cannot be missed!
