I'll try to find you one in the next few days. "L'hymne à l'amour" is really a great one but a bit old fashioned. Would you like a modern love song or a traditional?

In past days, there used to be songs "pour faire pleurer la mariee" and a great one (and my favorite one) start like this :

Nous sommes venus vous voir du fond de not' village,
Pour vous souhaiter ce soir un heureux mariage
A monsieur votre epoux aussi bien comme a vous (twice)

Celui que vous prenez sera souvent le maitre,
Ne s'ra pas toujours bon comme il a promis d'etre... (L'absence d'accent est volontaire)

The bride had to keep in mind that her good times were now past and gonegone and a maried life was very hard.
