There is little I need to say about these singers and Kempe's lyrical, dramatic direction of them. Nilsson is in great voice as she invariably was. Some of the top notes tend to sharpness (probably because of adrenaline) and her handling of the text, while sensitive and appropriate, would become more specifically colored in later performances. She had only been singing the three Brunnhildes for several years and this shows in any comparison with Varnay or Modl's handling of the text. But her singing is immensely satisfying; one never has to worry about whether or not she'll get the notes.Hopf is a sturdy Siegfried. He is neither the most beautifully sung nor the most interesting exponent of this role, but he'd be making a killing today. Frick is a saturnine, even sexy Hagen - a bass-voiced Bela Lugosi. Stewart and Bjoner are top-notch as the Gibichung siblings. Hoffman is a marvelous Waltraute, her voice solid as a rock from top to bottom, another fine singer often taken for granted. The Norns and Rhinedaughters are superb as is Kraus' angry, miserable AlberichThe sound is very good broadcast mono. One caveat: several lines are missing from the end of Act One after Brunnhilde screams when Siegfried takes the ring away from her. They are present in another copy I checked on YouTube; somehow they got lost in Andy's transfer. Minor point: Frick accidentally sings "Her dem Ring!" rather than "Zuruck vom Ring!" at the end.

Minor point: Frick sings "Her den Ring!" rather than "Zuruck vom Ring!" at the end. Whether this was a slip by Frick or a specific change by Wolfgang Wagner (this was his production) I don't know.
