Interesting! So this problem was widespread throughout the world! So we seem to know this much.
1) The original Pink Label UK releases were done correctly. Which would explain why Cat Stevens and the producer, Paul Samwell-Smith didn't catch the issue. They would have heard the initial UK releases. Which were fine. I doubt that they would have been concerned about worldwide distribution, and would have left that up to Island Records. They moved onto other projects.
2) The original A&M releases were faulty. A&M would have handled all of North America distribution and also the original Japanese pressings were distributed through A&M and released with A&M labels. So there is a good chance that they are faulty.
3) The problem in the UK seems to have began with the reissues on Pink Rim Island recordings. They would have more than likely made new pressing plates for the reissue. Which seems to be the standard for reissues.
4) We now know that the German Blue label suffered the same fate. It appears to be one of a plethora of German reissues with varying labels throughout the years. It does not have a date for the reissue. But it appears that it was a much later reissue. The original German 1970 release was issued with the Pink Label. The same as the UK release. It would be interesting to know if that first German release was done correctly.
5) In 1980, Mobile Fidelity released a 1/2 speed remaster, and in 1982 released it as a more expensive MFQR release. We haven't any information as to whether those remasters were done correctly. However, they definitely would have used the original master tape. They would have been purely analog remasters. Since digital did not exist in the technology at that time.
6) Then we jump ahead to The 2008 Island "Back to Black" Remasters. They would most likely have been remastered from the original master tape. There is no way of knowing if digital processing was used. However, they do not suffer from the same problem. And sound great when compared to my A&M first pressing.
7) And then of course. There is the 2011 Analog Productions. Which is when this issue was brought to light. At the time. Analog Productions had just built a brand new state-of-art analog remastering facility. Especially designed for remastering analog from the original masters without the use of any digital processing. To launch their new product and label. They chose TFTT as their first remaster. Since it was such a well recorded and beloved classic. They made a deal with Island Records for a limited release distribution. And were supplied with the original master tape. They even have a photo of the tape included with a description of the process as an included insert. Needless to say. They discovered the improperly decoded issue that plagued other recordings. And chose to do it correctly. They even decided to use the original Pink Island Label. And they sound fantastic!
8) Then we come to the 2020 remasters that Yusuf/Cat Stevens was personally involved in. They do not suffer from the issue.
This improper decoding issue seems to have been on an enormous scale. And have had an enormous impact worldwide. It was a colossal F%#%Up, to put it mildly.
I am curious if you have an original release Island copy of "Mona Bone Jakon"? It didn't do well at the time of its release. But riding on the heals of the enormous success of TFTT. The demand increased. And a reissue of the album was released. I believe that my A&M release of MBJ suffers from the same issues that my A&M TFTT does. I have nothing but the 2020 remasters that are streaming on Qobuz to compare it to. And they are being streamed at 44.1k/16 bit.
If you should have a couple of different pressings of MBJ. Would be willing to take a listen and see if you can hear the same issues with those pressings? I am curious. And if, by any wild chance, you should have access to the 1980 Mobile Fidelity remasters of TFTT. I would like to know how they compare.
What an interesting discovery. Thanks for all of the information that you have provided.
