What's a sweet song I could sing to my fiance/husband on our wedding day?

So my sister's wedding is soon and there's a long way between where I live and home. A drive will take about 12 hours. Normally, I take the drive, but my car can't handle the distance. Also, I am scared shitless of airplanes. Don't judge. It's a real phobia.

Here's the details. I am having a small intimate ceremony on the beach with less than 30 people earlier in the day, but the reception has 150 invited and starting at 5/6pm. I'm trying to argue I do not need a cocktail hour (saving (13.75++pp) because the point of the cocktail hour is because people are waiting during that in-between time while the wedding parties take photos. If people aren't even at the ceremony... why would they need to get to the reception an hour early to eat hors d'oeuvres?
