This is how the band Dream Theater during their 3,5 hour concert in London this February honored their idols.
It is an audience recording, so the quality isn't great, but it is listenable. Their singer, James LaBrie, kinda struggeled to hit all the highs and some of you probably won't like his voice, but it is a very hard song to sing live, so I think he did a good job. Instrumentaly, it's flawless. No wonder, because Dream Theater is a band of 5 virtuoso musicians. They are an art/progressive rock band playing very beautiful, complex (sometimes very heavy) songs with very deep lyrics.
P.S.: They also once covered a part of Bohemian Rhapsody and released it on their EP. They are big Queen fans.
