Ian Nicholls recalls interviewing the Beatles during their 1964 Australian tour, includes sound files.
John Lennon was "the most overpowering" of the Beatles, said Mr Nicholls.
"There was almost something hypnotic in his eyes," he said.
He asked John Lennon if he was confident the band could keep making hit records.
"I don't know if we can keep as many, you know the hits going so high, they'll probably level out a bit," said Lennon.
"There's still a couple of years left of making records that sell."
