My condolences on the loss of your father. This is a difficult and painful time for you; may the music help in your grief.
I just did a search under "links" above, and found that the search engine at "Cyber Hymnal" is disabled for now. You might be able to find the words there, but it'll take some searching on your own.
I don't know if you are in the US, the UK, or where, but if you can get your hands on the Hymnbook of the Episcopal Church (US), you will find what you're looking for at #645 and 646. I've heard it done at baptism, weddings, and funerals, and it's lovely.
