Lookig for a ride after the concert in Poděbrady (Prag to Berlin or Prag to Köln)

Good evening!
I am a huge fan and backer of KC:D. I am from Germany and my girlfriend and I decided to go to the Poděbrady concert of the Music of Kingdom Come next sunday, after hiking around the original locations for the weekend. We got everthing planned out in detail and we are already very excited about our weekend full of Kingdom Come!

Sadly, something at my work suddenly requires me to be in Köln (Cologne, Germany) on Monday around 8 AM. My company booked me a flight from Berlin, where I live, but that would mean I’d have to be in Berlin around 4.50 AM. But obviously, I couldn’t find a train or bus that takes me from Podebrady or Prague to Berlin (4.50) or Köln (8.00).

So my question is: Is anybody here attending the amazing concert and traveling eastwards directly in the following night, passing through Berlin or Cologne or someplace close? If I could find someone to travel with, I would be willing to give them a bag of gold and my heartfelt gratitude!
