Below is an illustration in why I have problems with the McCartney interviewed in August 1966.
The first set of stills are from an interview on 3rd April, 1964. It's the high arc right eyebrow McCartney. I have at least 70 images of him speaking, laughing, making different facial expressions. In each one, he couldn't bring that high arcing right eyebrow down if he tried. He'd have to scowl/frown so obviously you'd know he was doing it on purpose.
The second set of stills is from August 1966, Memphis, TN. His hair is brushed over his forehead, but you can still see some inconsistencies. The first two images are from the FIRST part of the interview, before they cut away to Lennon. The last image is from when they cut back to McCartney.
Call me mad (I've been called worse) but I think we're looking at two different McCartneys in the same interview. The first has the low brow. 1964 tells you with his hair brushed down that low on his forehead, seeing his right eyebrow is going to be difficult. But it's not. It's permanently hanging low no matter what expression this person keeps.
Then you get to the second stage of the interview where that eyebrow seems to be doing exactly what it's supposed to be doing, or what we're familiar with. You shouldn't be able to see it covered by that much hair. And you barely can in that last image. This is what you'd expect to see throughout. You're not getting that in Memphis.
These are stills from two separate interviews. The first one is the 20th December 1966, which many mark as the first appearance of "Faul". But his eyebrows, and the high arc tell you he's the same person you're seeing back in April 1964, and who you see very frequently. You're more familiar with this McCartney than any other.
19th July, 1967 shows you something different, and more in line with who appears in August 1966 in Memphis, TN. A man who cannot raise his eyebrow if he tried, to get the "trademark" high arc right eyebrow of Paul McCartney © 1942 (?????)
Now what I've seen for years is that LSD Paul in question anyway. Practically everyone notices something's amiss with the person speaking as Paul McCartney. This automatically makes a case for "Paul died in 1966, and was replaced by a lookalike for the remainder."
December 1966 tells you you're wrong. You've still got McCartney hanging around after November 1966, or any death date. The high arc eyebrow Paul makes appearances everywhere, in publicity photos, in promotional films, you see that high arc eyebrow more often than any other "shape or form".
So who exactly is this "other" Paul that I'm seeing possibly in 1964 in A HARD DAY'S NIGHT, on the rooftop of Savile Row in Let It Be, somewhere around the RAM era of 1971/1972, conducting interviews in Memphis, TN, but NOT Los Angeles, CA, in 1966, and talking about LSD in 1967. He also seems to be hanging around in April 1969, but I even have question about that one.

The following images all come from various issues of this magazine, and is yet another post illustrating a fluctuating eyebrow status. From left to right/top to bottom:
1962 gives us the "trademark" high arc right eyebrow. You find the end of his right eye with your mouse cursor, and go straight up. This is where the eyebrow reaches its highest arc point, then curves back down again to border the eye. Many photographs/interviews will show you he does NOT have to raise this eyebrow to achieve this "look".
1963, collarless shirt, is a very plausible "I pluck my eyebrows". Following that guideline end right eye/arc peak, IF he plucked his eyebrows, this photo would not prove anything other than he most likely plucked.
1969 (April) -- An anomaly, only questionable as to whether he is purposefully scowling/bringing his eyebrows down.
1969 (August) -- shows if he DOESN'T pluck them, how much hair he has there to pluck from. What should be observed is the very noticeable gap between his eyelids, and where that arc comes around to border. There is a LOT of skin there between these two points.
1969 (April) -- shows that no amount of plucking can give him this appearance. Too many discrepancies.
1969 (April) -- the SAME photo shoot, and apologies for the quality of image. But it can be seen that the guideline can be followed, the arc peaks right at the end of his eye. Which it does NOT do in the other shot from the same session.
