If you don't have this masterpiece in your music collection already then you don't have a great music collection and probably no good taste in music either. But having the old version is not good enough any longer.
This new 3cd deluxe edition is a must buy and I tell you why:
If you still want more (I bet you do!) then go here and listen to an extra album of rarities and a 1989 live concert from Dallas, both being streamed at high quality (and easily saved to your hard drive using a wave-recorder.)
So basically you are out of reasons not to buy this new 3cd. If you are broke then sell your mother or a kidney, you need this album more than both of them!
