EMI had already launched in the 1960s a 'budget' label called "Music For Pleasure" (MFP) in association with Paul Hamlyn Publishing, for the re-issue of back catalogue no longer considered of interest to 'mainstream' record audiences. In addition they had launched a new range called "Regal Starline" in 1967, again for budget releases but of more contemporary (and very often new) material that was considered to be more of novelty value than serious music (such as Rolf Harris and Kenneth Williams).
However, until around 1977, MFP and Regal Starline vinyl releases making their way to tape appeared in the 'Executive Series' instead (with any MFP or Regal Starline logos often clumsily obscured from the cover images).
The "all gold" look was adapted to this delightful blue colour scheme, with light blue inlays and labels, a dark blue Norelco case and a bright blue cassette shell!
It's interesting to note that during 1972/73, although the inlays used what is known as the "Mark II" EMI box logo, the cassette labels themselves featured the "Mark I" EMI box logo, as originally displayed on vinyl labels in 1969 (and on sleeves as early as '67).
Mark I had a single outline and lettering in a single colour, but the 'Mark II' logo had the letters 'EMI' always showing in a light colour on a black background, with a further outline adding a double edge to the black box.
Note in these examples the absence of the 1⅞ ips logo!
Another example of an early 'Executive' release.
In case you're wondering, EXE 7 was The Best of Rolf Harris!
For anyone who was slightly too old to develop an interest in Glam Rock in 1972/73, the Executive range was a good way for the slightly more mature record-buying public to replace their scratchy 1960s vinyls with what were then pristine sounding replacements.
