Reply To: Why was the National Anthem or G-D Bless Ameirica not sung by Siyum Hashas?

I doubt that the non-Jews would expect us to sing the national anthem at such a setting – akin to a shul or Bais Medrash. I think that singing the anthem at the Met would have been doubly inappropriate, as it would appear to be reverting the location back to its usual stadium status. A school graduation and the like are appropriate times for us to show our appreciation to our country.
