I’ve been using the plugin now for a couple months on our church band website with pretty good success. I’m working now on posting it publicly.
I’ve created a folder for it at http://lisles.net/ChordsAndLyrics.
I’ve also created a new category for specifically discussing it on this blog, and will use that category in links back to this blog regarding it.
The latest version 1.2 contains a Site Admin panel in Settings that can be used to select whether to display both Chords and Lyrics or Lyrics only. It also resolves the problem of lyrics wrapping around under a single Chord symbol when the lyrics length is long.
