Is there a definitive answer to the question?
As has been mentioned The Beatles entourage wasn't that big. So lets go back to the beginning therefore, who was in the Beatles entourage back between when May 1968(?) and August 1969 when Yoko was on the scene ? I'm rattling of the ones that immediately come to mind, please add others and delete the wrong ones.
George Martin
Neil Aspinall
Mal Evans
Billy Preston
Geoff Emerick
Magic Alex
Chris Thomas
Michael Lyndsay-Hogg
Allen Klein
Glyn Johns
Is this getting us anywhere even if we do approach it this way, do we know what each person's feelings were towards Yoko?
