One notable moment in pop music history is when Harrison brought Eric Clapton to Abbey Road to play the solo on While My Guitar Gently Weeps. Was Ken there? If so, what does he recall of the occasion?

“Well, I was at the session,” he confesses, “but it was just another day at the office so it didn't mean anything at the time. It's become part of history, but I don't remember anything about it. Chris Thomas, who was George Martin's assistant, remembers nothing about it. John Smith, my assistant engineer, remembers nothing about it. I've actually planned to do some regression therapy, hypnotism, to try and get back there and see if I can recall it. So I would love to be able to answer that question, but at the moment I can't.”

From the mid-’60s onwards The Beatles were musically on top of the world. There surely must have been a sense that between the band, its producers and engineers, they were making musical history…

“Not in the slightest,” Scott exclaims. “Obviously you know that there is importance to what you're doing. But to think that I would be talking about the records 60 years on… It was just rock and roll. Generally the artist had to come up with an album every six months, and if people were still talking about that when the next one came out, you've done your job.”
