Wayne, correct, the current understanding by us non-lawyers is that chord progressions are not copyrighted. Melodies can be, as pointed out, and therefore the whole song with your melody (and pretty much none of theirs) can be copyrighted by you.

There can be gray areas such as 'hits', specific rhythmic phrases that might only be chords but that make the one song instantly recognizable. I would stay away from those (not saying that they might be in the demos).
