The earlier stuff was better. It was, obviously, more revolutionary. They lost their way in the second half in a lot of ways. Once they did Shea they were a different band, they hated playing live, they stopped doing Sullivan. But, they evolved, and they experimented.
Back in the day, they just played music. Ringo and George knew their roles and stayed the heck out of the way. Yoko was nowhere to be found. The sitar was yet to make it mainstream. I like the mid-early years best. Beatles For Sale to Revolver, especially Rubber Soul and Revolver. Tomorrow Never Knows is as far as I prefer the electronic stuff to go, but it's all money.
I don't know, my mum is from Liverpool of that era, I grew up hearing all about it, she brainwashed me to have these beliefs it seems.
