The fact that the songs themselves and not just the album are compiled from various concerts shouldn't really surprise anyone. Most live albums are done this way .... even ones that claim to be from one show.
In fact, it's been common practice in the industry for groups, or artists, to go back into the studio and "fix" the live tracks. This is rampant on many live albums - ex: Kiss - Alive I, II, III & IV; Judas Priest - Unleashed In The East (which has been nicknamed Unleashed In The Studio); Thin Lizzy - Live & Dangerous ..... the list goes on and on and on. there are very few that are truly live, although they do exist.
At least, to our knowledge, Queen hasn't resorted to this. The tracks are still "live", even if pieces of songs are taken from different venues.
Just thought I'd throw my two cents in. Sorry for interupting.
I`m not surprised about fixing the tracks in the studio, because shit happens during a performance even though i think that Kiss and Judas Priest really abuse of this studio thing.
But to release two or even three performances in one song, i really never heard this was made, because it`s a lot more hard to do, instead of just fixing the mistakes!
What disapointes me the most is that Queen are considered to be the best live band ever -the BEST- but "Live Killers" is not the type of thing that the best live band should release, or Rare Live, or Live Magic.-"They should put their money where their mouth is, so to speack!"
I´m not been cinical here, but i do really think that Queen were considered to be the best because of the anthems and crowd reaction, because i`ve seen Van Halen concerts , bootlegs , or even Iron Maiden, and let me tell you, there`s no way Queen could beat those guys, because they`ve really worked very hard to be that good live. I think that the 80`s was the decade where Queen really established themselves as a very good live band.
Don`t get me wrong, their my favourite band, but there`s people out there that really work harder to guive the best concert they can.
When Steve Vai goes on tour with G3 he says that he can reharse until 15 hours a day, because he wants to be on top form.
Take care
