In the evening I joined Stravinsky, Mme Edwards and others in Diaghilev's box for the opening performance of the Ballets Russes. After the lamentable efforts New York has been making to ape the Ballets Russes with poor scenery and inadequate dancers, it was such a joy to see the real thing, albeit in a less extravagantly luxurious form than six or seven years ago. The Good-humoured Ladies to Scarlatti's music is highly entertaining and imaginatively staged by Massine, while the Petrushka was in a wholly different league to the New York production. After the performance I dined with Diaghilev, who was in a state bordering on rapture, dispensing champagne as is it were water, told a stream of stories and was magnificently in his element. Stravinsky got tipsy and made scabrous remarks, but was also a delight. A marvellous evening.
