delayed April Fool's joke

It didn't occur to me on Wednesday, when I wrote this:

Peter Susskind, a wry expatriate Brit, is my favorite pre-concert lecturer. He began discussing tonight's program by saying, "Like most of his symphonies, Anton Bruckner's Symphony No. 9 in D Minor begins with a string tremolo from which a theme slowly emerges." Then he began playing us a recording. After about ten seconds, enough time for perhaps half the audience to realize they were being had, he stopped it. "I'm sorry," he said ingenuously. "That was Ludwig van Beethoven's Symphony No. 9 in D Minor," which begins the same way. "This is the one I meant to play," and he gave us Bruckner's.

that the same concert would be repeated today.

Two points for your April Fool, Mr. Susskind.
