The title, if you search at Levy, is "Duet of the Two Men-At-Arms," or "Couplets des Hommes D'Armes" (see link by Kenny B.). 'Bold' does not appear in the title. No indication of the man who provided the English translation in the 1868 sheet music. More than one translation was used in presentations, which is the reason for disparity in the English texts so far presented. Gimpel and Barnett are two listed in the link by Kenny B.

The words of the 1868 sheet music at Levy still need some TLC.
1st verse, Line 1- To watch all the city's sleeping,
1st verse, line 3- Always an eye wide open,

Cho. line 2- We laugh at all, at all alarms,

and a few more minor corrections needed. The full title of the popular offering is Geneviève de Brabant."
