No time to dawdle — there’s a flight to catch. For an account of today’s recording session, I’m going to lean on Mark Lewisohn, whose writing is always direct and economical. I’ll be back in the saddle next week.

The Beatles did not play on this evening. Three flautists – brothers Christopher and Richard Taylor plus Jack Ellory – were recruited to add the final touches to “The Fool on the Hill.” Then, later in the evening, two viola players – Ken Essex and Leo Birnbaum – played on “Hello Goodbye”….

“All the Beatles were there,” says Ken Essex. “One of them was sitting on the floor in what looked like a pyjama suit, drawing with crayons on a piece of paper.”
