Prior to their July 1st concert in London's legendary Hyde Park, 65,000-plus concert goers, anticipating a performance by Green Day, regaled each other with what might have been the world's largest karaoke sing-along.

During the pre-show playlist, the sound man spun Queen's "Bohemian Rhapsody". The crowd immediately belted out the lyrics in unison, complete with humming Brian May's guitar solos.

The crescendo, at about the 4:00 minute mark, shows the crowd bouncing up and down in delight simultaneously.

Surely, Freddie Mercury was looking down on all of this with approval.
