I'm sorry, was there a question there?
All I see is a random series of words that make neither a question nor a statement.
Perhaps try it in your own language - this is usually frowned on but I think we may do better putting what you say through an online translation tool than trying to decipher what you might mean.
Let me try...
1. Is it true that the Saarbrucken concert was full of technical problems?
2. Did Roger have green hair at that concert?
3. How was the band feeling that night (I would assume in a performance-based way)?
...am I right?
Due to a bad monitor onstage Roger trashed his kit after the show... complete with green hair. Though Freddie did ridicule him during the show which was in good fun the sound on the stage for Roger was a key factor in the "timely" death of his drums.
