Okay, okay..... I'm just getting caught up with this Pink Floyd stuff!
Me back when I was stationed in Germany.
Yes, we had to get clearance to pass through check point charlie on the Soviet side.
It was the largest concert I have ever attended. Some say 250,000, some say closer to 500,000 all shoved into Potsdamer Platz, Soviet's "no man's land" where many died trying to escape to West Berlin.
Was unreal, even at today's standards.
Side note: kinda stuck on "Animals" and "The division bell" as my favorites. Saw them on the "momentary lapse of reason" tour here in Saint Louis.
