General rehearsal of Seven, They Are Seven, the only rehearsal involving both choir and orchestra. It began problematically, as the tenor had not realised it was due to start at ten o'clock and was extremely put out that nobody had informed him. In short, a huge to-do ensued. He wanted to cancel, and it fell to me to persuade him otherwise, a tremedous argument at an extremely inauspicious moment. He has a piercing little voice, not particularly beautiful, but he is a good musician. Seven, They Are Seven in a big hall sounded less menacing than I thought it would. The chorus or eighty to ninety people really needed to be a hundred and fifty. The tam-tam player was dreadful. I was a prey to terrible nerves because it had got off to such a rocky start, but Koussevitzky made a great effort and by the end had everything under control. By the time I returned home I was utterly exhausted.
