This is what is Shot:
Milton keynes England: in complete form.
Vienna,Austria:the footage you see on disc two on the Milton Keynes DVD.
Frankfurt,Germany: On "rare live" they show a clip of "Tie your Mother down",which they claim is from Frankfurt,but this could also be from Vienna because they also claim that "We are the champions" is from Frankfurt and that one is from Vienna. If "Tie your mother down" is from Frankfurt,its proberly all they got.
USA,Saturday night live:"Crazy little thing called love","Under pressure".
Japan,Seibu lions:60 minutes version released in Japan only,25 minutes is shown on milton keynes DVD.The audio recording exists in complete form,the used "Calling all girls" om the DVD.
The Tie your mother down part from '82 from Rare live is definately from Frankfurt because it's exact the same as on the audience recording from that show if you just listen closely to Freddie's vocals. The soundquality of the audience recording from Frankfurt is Excellent so it's easy to compare then.
Peter Freestone said they recorded everything during the European leg. Since there's no proof, I agree it doesn't seem likely at the moment. Don't know if I'd call it "bullshit" though.
