Incredible behind-the-scenes video has emerged of Queen rehearsing their iconic Live Aid set

It has since been labelled as one of the greatest live performances of all time ... and now video has emerged of Queen rehearsing for their 1985's Live Aid set.

Their iconic 22-minute set - which was performed by Freddie Mercury, Brian May, Roger Taylor and John Deacon at London's Wembley Stadium - saw the rockers belt out six of their biggest hits, including 'Bohemian Rhapsody', 'Radio Ga Ga', 'Hammer To Fall', 'Crazy Little Thing Called Love', 'We Will Rock You' and 'We Are The Champions.' 

But while the performance on the day looked completely effortless, Queen had practised for the set at length, with the resurfaced video documenting the band's rehearsals in the days leading up to the historic event.

Live Aid was one of the largest-scale satellite link-ups and television broadcasts of all time with an estimated global audience of 1.9 billion, across 150 nations, watching the live broadcast.
