For those interested:
The Queen official page on youtube just posted the "new" oficial video of this performance. It has different camera angles than the one that was streamed. The quality is great! link
The more i see this video the more i realize that this was Magic in the making. The first time they have performed this song, and it was flawless!
The surprise element was there, and this is very special. I hope they release this performance in the future coupled with the other concerts they are filming, because i saw this live with the streaming, and i'm pretty sure that those who were connected around the world with this moment will never forget this performance.
