Vikram has got yet another star onboard for his "Spirit of Chennai" song. The latest celebrity to join him is none other than Bollywood actor Abhishek Bachchan.

Abhishek Bachchan joined the shoot on Thursday, 7 January. He had a fantastic time with Vikram and his team. Prabhu Deva has also taken part in the special song.

Sources say Abhishek and Vikram are close friends. It just took one phone call from Chiyaan for the Bollywood actor to come to Chennai to be part of the track. His gesture has been appreciated by the actor and the entire team. Meanwhile, Malayalam actor Nivin Pauly also too took part in the shoot.

So far, Jayam Ravi, Jeeva, Varalaxmi Sarathkumar, Suriya, Sivakarthikeyan and many others have taken part in the shooting. Kannada superstar Puneeth Rajkumar, Yash, Telugu actors Prabhas and Ram Charan Teja will be making guest appearance in the number.

"Spirit of Chennai" is a special song directed by Vikram as a tribute to the volunteers and the citizens of Chennai who stood strong when unprecedented rain led to floods and wreaked havoc in the city last month. People then united to help others cutting across all barriers, and the song praises such acts that brought out the best in people.

Meanwhile, Kamal Haasan and Vijay are also expected to join the shooting. The audio song, with devastating visuals of the flood, was released recently. The actual video featuring the celebrities will be released soon.
