This first the first time I ever uncovered the rebus theme myself! I was so stoked! That was fun, thank you!

As someone from and in Bremen, I would like to remark that St. Pauli (the football club, the borough, and also associated beer if any) is in Hamburg. Becks is from Bremen. And the four town musicians.

As a German speaker, I'd like to express my boredom at 99% of the clues requiring me to write "Ach". The word is not used like most clues imply. I wish puzzle makers would improve the clues, or stop asking for the word.
