Organised by Bollywood directors Karan Johar and Zoya Akhtar, the show, called I for India, will be live-streamed by Facebook and pay tribute to workers fighting the pandemic.

It aims to raise millions of dollars for more than 100 groups providing food and other essential services during the crisis.

 Concert organisers said the money was needed "for those who have no work and no home and do not know where their next meal is coming from".

India's 1.3 billion people have been under lockdown since March 25 with the restrictions, while recently eased, set to last until at least May 17.

The shutdown has especially hit millions of migrant workers stranded in cities with little food or money. Special trains were being organised Saturday to help thousands of labourers finally return home.
