Thanks for mailing these 'old' concert tickets. Made me dig through mine again. (picture is gone) 
Here's The Wall. 21 july 1990 Berlin.
After standing in a crowded train for a long time I remember walking through former east Berlin. With a friend and a bottle of wine. Like in a dream.
The volume of the concert was very low. The public was shouting 'LOUDER!...LOUDER!' the whole time. That's about the only thing about the concert I remember.
