(We didn't do a unity candle or a sand ceremony but I have played for a couple of my friend's unity candle lightings.  I played Meditation from Thais and Be Thou My Vision)

We used  "One Hand One Heart"  from 'West Side Story"  -  my MIL mentioned she had seen this used before , and we thought it was appropriate not only because of the lyrics but because it is from a musical play , and our kids perform in plays all the time ... it added a little "theater" to our wedding music ;)

I have been thinking about using Elton John's "Circle of Life".  I have heard of people using this before and I just adore the song.
