MOP, Bk 7, v.4, 62
“3. The National Anthem should not be played and sung for mere recreation, amusement or entertainment purposes in social gatherings purely private in nature or at political or partisan meetings or places of hilarious or vicious amusement. It should, however, be sung in schools so the children may know it by heart. It may also be played during the ‘signing off’ but not on ‘signing on’ of radio broadcasting stations.”
Done in the City of Manila, this 10th day of April, in the year of Our Lord, nineteen hundred and fifty-four, and of the Independence of the Philippines, the eighth.
