I had just just finished rewatching the unexpected magnificence that is Russell Brand on Morning Joe when up came a wonderful memory:
Green Day at Emirates Stadium 1st June 2013 - the crowd sing Bohemian Rhapsody
On Green Day's current tour, Bohemian Rhapsody has been played over the PA as the signal that they're about to start. We all know this by now, so the instant the track started everyone stood up and got ready to give it their all. I've chosen this particular video of the song to keep as a special memory because it highlights how loud and how lovingly the crowd were singing.
