Here's another verse to this song (which may not need another last verse), from one of my Rivendell Co-op housemates in Michigan; we used to joke about someday we'd all be sitting around gray-haired, and this verse would catch up with us. Rediculous!
The years went by, and time's now left us; Your face is lined, and your hair is gray; But I'll tell you again, how much I love you, With this simple song, in the same old way.
