Had to think back to when I wrote this one- and in going through my files, I realize that (unlike many of my songs) I seem to have never kept the original handwritten lyrics. Only file copy I have is the original typed lyrics- and even weirder is that I've never redone them with the chords included.!!! They date back to somewhere around 1995, but I worked up the posted version a few years ago. Indigo is a deep shade of blue, and fits well with how sometimes we really feel the blues- but something can always get us past them. Maybe something we love- maybe someone we love. Whatever it is, it's worth working for.
