The problem with Queen II (my favorite as well) is the March of the Black Queen, Ogre Battle and the Faeri Feller’s Master Stroke could not be played live due to the over production. A band I was in played a stripped down Ogre Battle. Underneath is still a great rock song.
This was an issue with Bohemian Rhapsody too. I saw Queen live three times after "Night at the Opera' came out and each time the first half of "Bohemian Rhapsody" was played canned from tape and the band didn't step in live until May's blistering guitar solo.
