Quick question to the flist, because I know at least some of you were either born already to know this or at any rate would have more of a background in music than I do off the top of my head: by when, date-wise, had the "sound" of the Beatles changed to a point where the Average Vampire Man In The Street would say of the later stuff "I can still identify that as them but that's a leap"? Because I know there's a break you'd loosely call "WTF Sgt Pepper??!?", looking back, but not having lived through the period in question I have no intuitive sense of what the progression would have seemed like to someone experiencing it over time...
