"To the modern mind, musical skills and police responsibilities have little in common, but in an earlier age the two roles often overlapped. Musicians not only helped defend the city gate, but might also be required to patrol streets at night. In Norwich in 1440 a tax was instituted to pay the waits for their watch—and these musicians were required to take an oath of office. In Germany, a minstrel was expected 'to acquit himself well as a swordsman.' Surviving illustrations tend to emphasize the bulky, formidable aspect of these street performers."
