Ok, thank you for your input. I have no idea about the provenance of the magazine as it was in a box of stuff in my loft. I did know the chap who claimed to have gotten the album signed though and I did believe him… though obviously people don’t always tell the truth!
Unfortunately he is no longer with us so I can’t ask for more details.
I’m not arguing the point as I have no knowledge on this subject but may I ask what leads you to your opinion on the Lennon one?
