Love / Polish wedding traditions/ toast ideas [9]

Dzien dobry,

My son is getting married in two weeks. I've been asked to give a short toast. Are there any special Polish toasts, blessings, etc?

Both of my parents were Polish....and both died suddenly before my son's engagement. I had always hoped to rely on them for Polish traditions with respect to weddings....but it wasn't meant to be. I have no other Polish relatives living / nearby. But, I would like to incorporate some tradition if possible.

Any input would be greatly appreciated.
