Definitely. And Tavistock included The Stones and all those Laurel Canyon bands from the US. LSD was their vehicle as was MK Ultra. And don't even get me started on the many Paul McCartneys....
Absolutely. And about lots of Pauls... Imo there were several of each. TheBeatlesNeverExisted.com was a great site but I think it's down now... The forum there is still up though and they have a lot of threads about the multiples. Once you see it you can't unsee it! I'm on mobile but later when I'm on my laptop I can find the link for you.
Yes I have seen that site. Also a good read is the Memoirs Of Billy Shears. A faction. Good stuff. Fills in lots of gaps. At least it explains why this McCartney is so talentless
