The Dutch Wilhelmus is the oldest national anthem in the world. The first stanza is the part that is usually sung or played at official events. We're guessing that the part in the second stanza about being loyal to the king of Spain doesn't get much airplay these days.
William of Nassau, I am of Dietsch blood, My fatherland, I am true until my life is though.
I am a prince of Orange fearless, ever free, The King of Spain will have my lifelong loyalty
Or as the locals sing it:
Wilhelmus van Nassouwe ben ik, van Duitsen bloed, den vaderland getrouwe blijf ik tot in den dood.
Een Prinse van Oranje ben ik, vrij onverveerd, den Koning van Hispanje heb ik altijd geëerd.
