Yes, it was Harrison's Elegiac Symphony that you played that year. I do have a note of that.

B. remembers Chavez's slow, placid way of directing the chorus.

Of course Cage enjoyed the boos. He wasn't a composer, he was an imp. He just wanted the audience to react, to respond, he didn't care how.

But if you're going to write music like that, that's a very wise accepting course to take. Some don't get that. I remember about that time an SFS audience laughing at the silly pompous work of George Crumb. Ozawa looked furious.
