Just a note, Florian hasn't played with Kraftwerk since he left (retired?) in Nov 2008... so you wouldn't have seen him anyway. I sure hope that tour goes on once things return to normal!
I'm in the same boat. I tried buying tickets for European shows last year but didn't succeed. And now the show is coming to USA town, I get 4th row tickets and bam... Disappointment all around.
Florian left Kraftwerk years ago though, you weren’t going to see him anyway :)
