An advertisement for this event was published by Prager Morgenpost 1/10/1863. The source announced:
Today
as well as every Sunday and Thursday
plays
Carl Komsák [Karel Komzák]
with his large Orchestra
in the Hall of Mr
J.M. Schary.
Commencing 7 o’clock Admission 10kr.
Specifying ‘plays Karl Komsák with his...’ may have been an indication that, as was often the case with popular salon orchestras of this time, the band was led by Komzák playing the violin.
