Brian Wren is a prolific hymn writer. Perhaps he is the one you are looking for. I can't find anything with that specific text, but if you go through any of the denominational hymnals, you may find what you are looking for since you will find numerous hymns by him in any of those--the UMC, Presbyterian, Lutheran or Disciples of Christ (Chalice Hymnal). He has written an epiphany hymn---What was your vow and vision---which I found in The Chalice Hymnal. There is one the The Presbyterian Hymnal for Baptism of our Lord called Lord When You Came to Jordan. Unfortunately, without the text or even partial, it's tough. Sorry.

I heard a Presbyterian pastor talk about this hymn written by Brian somebody? But I really like one of the lines from it for this season of Epiphany. It talks about "the joy of seeing and the discomfort in being seen." unfortunate that's all I've got.
