On Lundy Island, some of the ones they had for the wedding was "One More Step along the World I Go" and "Lord of the Dance"
Also you could add "I love you with the Love of the Lord", "Bind us together"
At the wedding of the son of a couple in our church, we had one called the Greatest Commandment
For those unfamiliar with it, this is a version of it.
(Eagle eyed people will spot I used this in one of my Mystical Realms tales)
(incidentally The son and his bride were members of the congregation in their own right and after they got married moved down to Reading)
Funeral wise - "Abide with me", "Blest be the ties that bind", "It is well with my soul" and possibly "The Day thou gavest Lord is ended"
