@slaw - I took another listen of "Demons and Wizards" today, in a better frame of mind, and it sounded much better. Took a look at Discogs and found it is an early US Mercury Bronze release. I'm not an expert on LP Labels, runout markings, etc., but here is what is on my copy:
Label variation: Red Label with Philips, Mercury, and Vertigo logos at the bottom of the label and Bronze logo in the center.
Matrix / Runout (Side A Stamped): SRM-1-630A-M1 GK
Really enjoying it. To me, several of the cuts sound similar to another band I really enjoy - Procol Harum.
