Unfortunately, the copy I had was a little noisy (may be due to over-playing). As some promos of the "bigger" releases on Warner in the '80s were pressed on virgin vinyl, I set out to find a promo, and also to find other pressings.
This one I found was excellent! A totally quiet background, and hence playing a bit more dynamic than the regular run-of-the-mill pressings. A German pressing I found was almost as good. Since the entire promo run was probably pressed on this Quiex vinyl, they should not be too difficult to find.
