I don't think so - the memory is faint for me, but I remember it being in the news back then. It was at a time when Lennon and McCartney were suing him, not sure if the suit was about that quote or not.
I found the quote
here - it's where I got the exact wording.
When Harrison said that, I don't think ELO was quite off the ground yet, but Lynn was a member of one or two other 'beginner' groups before ELO. Lynne was English, as was Harrison, it wouldn't be hard to imagine those two meeting up at that time.
Many years later, they played together with the Traveling Wilburys!
