I believe the song you are looking for was done by the Nelons back in the 80s or so. It's called Wedding Day. Although Rex Nelon passed away several years ago, his daughter and son-in-law still have a group called the Nelons. Search for them online and ask them about the song Wedding Day.

chorus- and we will fly away in the twinkling of an eye we'll leave behind our troubles and won't tell this world goodbye. it's something like that! if someone could help and finish the song it would be greatly appreciated!
