‘Those two boys operated on a different frequency. [John] Askew (Johnny Gentle) says of Paul and John. “I used to watch them work the crowd as though they’d been doing it all their lives - and without any effort other than their amazing talent. I’d never seen anything like it. They were so tapped into what the other was doing and could sense their partner’s next move, they just read each other like a book.’ It was uncanny, he thought, how well they knew each other. 'It was always Lennon and McCartney, even then. Lennon and McCartney, They wouldn’t even look at George or Stu to determine where things were going. Everything was designed around the two of them - and the others had to catch up on their own’.
