Perhaps unsurprisingly, Queen and Adam Lambert completely stole the show. They actually performed the Live Aid set! Almost exactly as on that day in 1985. Started with Bohemian Rhapsody, then transitioned mid-guitar solo to Radio Gaga, then they dimmed the light and had the video of Freddie doing the EY-YO with the crowd, then they did Hammer to Fall, then Adam gave a little speech, then they did Crazy Little Thing followed by We Will Rock You and We Are The Champions.
Probably the moment of the day though, came right at the end. John Farnham (and wow he is still amazing) was readying the crowd for You're the Voice...and out comes Brian May with his guitar to play the song. Cue 70,000 simultaneous freak outs.
