I have that 21st November 1988 Platterlog sheet! How the heck did I miss this? Must have had an off night. Also released on LP, for those that are interested.
Hi PhilMH / Whassup, I stumbled on the Platterlog entry for this while attempting to find something else. Platterlog entry date is 21/11/1988 making your "1988/1989" estimate spot on PhilMH.
I haven't been able to find a date for this - Michael De Looper's latest EMI albums listing has this number as an unfilled gap, with nearby filled numbers suggesting that it would have been a 1988 or 1989 release, but there's nothing for this in my Platterlogs from that time. It does look 80's to me, though, particularly because of the barcode, so either it was released in 88/89 and didn't get into Platterlog for some reason, or Michael's slightly off with his dates and it was released earlier but deleted before August 1988 (the date of the first Platterlog that I have). It was also released on LP, which Discogs has (undated) - I don't know where the 1977 copyright date comes from, though, because there's no UK or other country release from that year.
