I just finished putting up the next two lessons in Secrets of Chords and Chord Progressions and guess what? The lesson dealt with the "Blue Moon" chord progression: I - VI - II - V. This is the second chord progression Scott mentioned early in this thread. Here is a direct link to the lesson:

The second lesson (week 30) deals with embedded chord substitutions for this chord progression.
