Once upon a time you two met
You’ve shared much love and laughter
May your marriage be a fairy tale
Happy ever after
I’m glad I’m in the fairy tale
And you are too I guess
Congratulations, King and Queen
From your fairy tale Princess
for a boy, the second verse could be
I’m glad I’m in the fairy tale
The future’s looking bright
Congratulations, King and Queen
From your loyal, courageous Knight
