Some great info. Thanks. Now, I have more to look for. I do not have Mona Bone Jakon. I think I had it on 8 track or possibly cassette ages ago but it is no longer in my collection. It was not a favorite of mine, as I recall or I would have replaced it long ago. My other favorites would be Catch Bull at Four and Buddha and the Chocolate Box. I just picked up an Island copy of Catch Bull at Four and look forward to comparing it to my A&M copy.
Others that I have are The World of Cat Stevens on Decca.
Very Young and Early Songs on Deram/London
Matthew & Son two album set on Deram/London
Cat Stevens Greatest Hits on red vinyl A&M
Teaser and The Firecat on Island, two copies
Catch Bull at Four A&M and now an Island copy
Back to Earth promotional copy A&M
Buddha And The Chocolate Box A&M
Izitso on A&M
Numbers on A&M
7 copies of TFTT, Island original pink label, Island pink rim, Island German blue label, two A&M copies and the off-center re-issue from Universal and the A&M dbx copy.
I think that's it but often adding more. I'm going to have to check the other albums to see if I find any similar issues. Most are A&M but I always thought they were well done. Have more to compare now so will be interesting. I've certainly learned a great deal on this subject. Thanks for all the info.
