John was a loose cannon, always was. The "toots" and excesses thereof are detritus of the going downhill fast early '70's. As for Harry, everybody was always talkin' at him but he didn't a word they were saying. . . probably because of too much tooting. It's no wonder that she--whoever she was--left him. But this is just the way the story goes in the .those days of excess and confusion, after the British invasion, after the gold rush, after our US gov finally got the message and forsook Vietnam and the boys started coming home again and got back to work again, as Americans are s'posed to do, insteading . . . uh, tooting.
Meanwhile, back at the Apple ranch, Paul and Ringo were holding down the fort until John could tear himself away from westcoast tooting and get back to where he once belonged.
But in the end, John did not do himself in with excesses. He was taken out by a tragic criminal act. That was true Shakespearean tragedy. The final verdict on the fab four was after John was gone and Paul donned wings to fly to Scotland and settle into a life of love and music productivity.
As for Harry, who knows? Who cares? But I guess that's just the way the story goes in rock music. In the end, the music you take is equal to the music you make. As for love, really when you get down to it, in the end, it's all you--or I, or anybody else-- really need.
Much more so than tooting.
