You can always google wedding songs and lyrics and it usually takes you to the wedding directory type sites and they have lists for every possible moment you could think of plus some i have never heard of!!!
I am getting married june next year and we are having Alicia Keys ' If I aint got you' for our first dance, a instrumental piece called 'Rose" from Titanic soundtrack which is pretty much my heart will go on but with more of the irish flutes and our goodbye song is by Andrea Boccelli called "time to say goodbye" which is in Italian and gives me goosebumps everytime i hear it! But no idea what else yet lol goodluck
