Even better than that Cage was also there to interact with the students. So in one class we got to hang out with him for an hour asking questions and him telling stories.
The Cage biography “The Roaring Silence” by David Revill is a good read. Lots of interesting little bits, like Cage lived next door to John & Yoko and introduced them to the macrobiotic diet. But my favorite is from when Cage premiered his famous silent (not really) piece 4’ 33" in Woodstock (the artsy town not the festival). Afterwards a local artist in the audience yelled “Good people of Woodstock, let’s drive these people out of town.”
