Something else that seems relatively foreign from a lot of 'modern' music today (of most genres) is that the entire unit stayed together for... 90%+ of their career. Beatles/Martin @ Abbey Road comprises most of their output, with some engineer changes here and there, and a bit recorded at other studios. Compared to today, where everyone switches producers every album (or on the same album), staying mostly in the same place with the same group of support people for... 7 years is relatively remarkable, and, I suspect allowed them all to grow together in various ways.
