An advertisement was published by Mercy’s Anzeiger 4/11/1854 announcing:
‘National - Song - Concert [National - Gesang - Concert],
which this Saturday 4th Novemb.
in the Guest house
„at the King of Austria“
at Poříč
by the Siblings Hann. and Ru-
dolph Barger from the Tyrol, with Schlag- and
Bowed-zither accompaniment. Commencing
at 7.30 o’clock.’
The description ‘national’ was probably used in the sense of ‘folk’ given the performers were Austrian Tyrol zither players.
