Is it appropriate to sing the National Anthem while saluting the flag?

Yes, it is appropriate to sing the National Anthem while saluting the flag; however, since it may be somewhat awkward, unnatural and incongruous to render the military salute while singing, it is permissible to remove the cap with the right hand and hold it at the left shoulder, the hand being over the heart. It is noted that this section pertaining to the National Anthem does not contain the “remain silent” clause associated with the “Pledge of Allegiance.” ( Americanism Commission)
