I was on a Piccadilly line train Saturday morning and the driver
announced that it would not stop at Green Park. It did, in fact, stop,
but the doors did not open and I could hear announcements in the station
telling people to evacuate. Later in the day the station seemed to be
fine.

Can anyone tell me what happened?

Defective public address system. Just to settle all the arguements later in
the thread.
