Is there anyone here that is part of this organization ?
Or perhaps willing to find out what company was responsible for the conferance call?
I don’t know of any company that uses a song about the Kaiser in a foreign language as hold music.
As soon as I read that, I thought, "Hmmmm...no 'accident', at all!"
The NYC 311 line often has classical music for those
on hold. There’s a Haydn concerto with the same or
similar tune, which would date from the 18th century.
Never heard it on hold though.
