What was a revelation was the ballet itself, performed whilst the audience actually did catcall and boo. The revelation was that it seemed so contrived and dated, hardly revolutionary at all and not terribly interesting. It is perhaps significant that when Diaghilev came to revive The Rite of Spring in a subsequent season, no-one could remember any of the steps (and Nijinsky was too ill by this time), so that Massine choreographed an entirely new score.
One piece of history was not re-enacted; the moment when Nijinsky gets so annoyed with the dancer playing the Chosen Maiden that he demonstrates the choreography himself. The result was to startling that everyone agreed that it was a shame that Nijinsky did not create a role for himself in the ballet. The dancer playing the Chosen Virgin was in fact chosen because she was the tallest in the company, not the most gifted.
The ballet classes and rehearsals had an interesting element of realism, the 'dancers ' did not all have the perfect bodies that we anticipate nowadays!
On a final, picky note, I was worried that Marie Rambert was referred to as Marie Rambert, I suspect that she was still called Miriam Ramberg at that time, though again I'd have to consult the biographies to check.
