I'm a huge fan (obviously). I've seen Queen with Freddie once, with Paul Rodgers once, and now with Adam. I've also seen Brian solo once and met him after the show.
The screen cap has the user name for the YouTube account in the bottom right, Edwin4NOH8, plus the title at the top. He only recorded the songs Adam sang so he didn't post a few songs the were just Brian or Roger playing or singing, but you can find those all over YouTube.
