Dream Girl is my favorite too (obviously--i.e. my signature) and I sing it to my baby as a lullaby. I also sing her the one that goes "Out of my window, looking at the night / I can see your anchors shining bright / Swiftly flows the river to the sea / And your anchors do go silently / D G, I would like to go with you / I would like to sail the ocean blue..." She loves both of them!
I think the problem that most people are having is confusing the DG songs that are used for all the rituals with the chants (even the chants that are sung to a tune) from recruitment. That's why some people are like "I've never heard of that song..."
Also, I'm not sure if the song that Delta Iota sings for Senior Installation is a chapter thing, or if everyone uses the same one...but if there's a DG from UGA reading this, could you post the lyrics? I love that song and I tear up every time I hear it, but I can't remember the words.
