Query: A Few Gems as Few that are better on later releases

Its a 4 track demo, so the fact that some songs are early versions of things later improved upon isn't much of a surprise. There are a few tracks that are just great and do not appear on later albums (not sure why because they are damn good). So, for a non collector type like me, it was still a worthy purchase.
