Playback singer Sonu Niigaam has created an anthem for Mumbai's police force to praise the spirit of both the security personnel and the average resident of India's financial and entertainment capital. The song has been created as part of the police campaign called Abhedya (Invincible) Mumbai.

Composed by Sonu and written by Subbu, National Creative Director of Linterland, the song opens in the voice of superstar Amitabh Bachchan. It was launched exclusively on BIG 92.7 FM on the eve of 26/11.

"This song means a lot to me first as a Mumbaikar and then as the lyricist. Working with Sonu was an awesome experience and Mr. Bachchan opening the song was a dream! I am glad we all got together to create Mumbai's first anthem. I hope people like our effort," said Subbu in a statement.

Big B is joined by leading singers like Jagjit Singh, Talat Aziz, Suresh Wadkar, Shankar Mahadevan, Sunidhi Chauhan, Alka Yagnik, Shaan, Kunal Ganjawala, Kailash Kher, Roop Kumar Rathod, Mahalaxmi Iyer, Richa Shama and Hariharan.

Abhedya Mumbai is an effort to spread the message of solidarity and security amongst Mumbaikars with an endeavour to channel youth power towards unity and integrity.

Its next phase includes a large-scale concert by leading artists of India, managed by BIG Events for the Mumbai Police.
