The world’s biggest music stars gathered in one room for a historic recording in 1985.

That event is now featured in a new documentary called ‘The Greatest Night In Pop’ that premiered at the Sundance Film Festival Friday and starts streaming January 29th.

Producer Lionel Ritchie – who performed that night – says there was not lot of ego because everyone realized they were trying to save lives.

‘We Are the World’ raised $50 million dollars for African famine relief.
