from Gered Mankowitz's The Stones 65 - 67, about the cover shoot on Primrose Hill in London, late in 1966:
"Between the Buttons was in a way my first attempt at conceptualising an image, and for various reasons we did the session early in the morning, but primarily because [the Stones] looked fantastic at that time. There was a look to them at dawn, after working through the night, that had a special quality. And there was something really special about being on the streets at 5:30 in the morning, when it was completely deserted.
"But it was cold and I knew I wouldn't have their cooperation for long, and Brian was becoming increasingly difficult. At one point I got quite upset because I felt he was ruining the pictures, but Andrew just said, 'Don't worry about Brian. We are at the point now where Brian can do whatever he likes. He can't fvck the Stones up. He can only contribute to the Stones' image, whatever he does.' And he was right.
"... I wanted these strange compositions, as if the band could disappear into the atmosphere, so it was a bit ghostly and a bit acid-y and always trying to get away from the smiling, clean-looking thing."
Andrew Oldham, in the introduction to the same book:
"Mick, Keith, Charlie and Bill, with a minimum of moaning and 'come on, Gered, it's bleedin cold, get a @#$%& move on, dear!' were on for the shot and up for the occasion ... The time came when the four Stones knew, from experience and instinct, that Gered was close to the series of moments that counted, and they gave him that extra zap, pulled themselves up and delivered the spark that separates the men from the toys. ... The Stones were suddenly there, Gered was there, the picture was there, taken. Our time was up, the light had changed, the day had moved on and belonged to others ... [This shoot] had been very close to the wind, stealing time that in minutes would be gone, on Her Majesty's property without a permit. ... It would be, and is, my favourite album cover."
