The story I heard is that one of the reasons the Beatles broke up was that they were upset that Paul was spending so much time on the song “Maxwell’s Silver Hammer”, which may have been the first song by a major artist that used a synthesizer.
It certainly could be true.
That said, they were breaking-up before the Abbey Road album from a myriad of forces including that witch from Japan. There were significant concerns about the financial management.
The White Album is kinda special to me. I was a 19y/o kid when I moved from Ohio to Hollywood. One Sat afternoon I was listening to KHJ on my cheap clock radio sitting atop my refrigerator.
They were playing songs I had never heard and the “DJ” was telling stories about each track or what was occurring in the studio.
The DJ? George Harrison
The Album? The White Album
I bought it a week later at a shop on Sunset.
