QUEEN's official YouTube channel has uploaded a one-hour film which finds the British rock legends at the Rock In Rio festival in Brazil in January 1985, performing over two nights.

It was one of the largest music festivals in the world, with each show watched by nearly 200 million television viewers in over 60 countries.

More than 350,000 people were present for the QUEEN shows, setting a world record for the biggest paying audience ever at the time.
