I ask you please Rabbi to tell me if I am correct that you said in the name of the Rov, if you are at a baseball game and the national anthem is being played, it is OK to remove your kippah out of respect for the request 'to please remove your hat for the playing of our national anthem'. I am always uncomfortable with this request when I am at a game, but I do not want to believe I have permission from the Rov without being sure. Your 25 year virtual student, Boiruch PS I listen to every shiur so please answer via a shiur or email.
