Amitabh Bachchan sings Rang Barse in local train

Amitabh Bachchan recently traveled in a crowded local train in Mumbai to lend support to Saurabh Nimbkar, who had appeared on his show Aaj Ki Raat Hai Zindagi.

Saurabh plays the guitar everyday while commuting in the train to raise money to help poor cancer patients.

Big B appreciated Nimbkar's noble gesture in his own way.

The superstar surprised Saurabh and train commuters when he took a ride in the local and entertained everyone by singing his popular number Rang Barse.

Later, Big B tweeted pictures and wrote, 'Local from VT to Bhandup to support Saurabh, who sings in locals for charity to cancer .. sang with him.'

The superstar penned down his experience on his blog too.

He wrote, 'If there is a conscience that has pricked my mind and heart, then it does become an imperative exercise to follow it through with deed .. personally.'

'Saurabh Nimbkar, sitting to my left in the picture, that came on our show #AKRHZ .. plays the guitar and sings on local trains and collects the meagre money he gets from co passengers, to distribute to the less fortunate cancer patients and their families, in the city .. his story was heart breaking .. I felt I would want to sit by him and travel the distance he does, do what he does, in a show of support and spirit for his incredible thinking.'
