For Paul McCartney, the decision to fill most of the Beatles’ albums with songs composed alongside John Lennon — rather than those of George Harrison and Ringo Starr — came down to productivity.
“There’s only four people,” McCarney told Howard Stern. “So you’ve got to go: ‘Well, two of us will do this.’ Or you’ve got to say: ‘We’re all going to write equally.’ Well, in that case, Ringo better up his game a bit — because John and I were writing; George and Ringo weren’t.”Over time, of course, Harrison began grow by leaps and bounds as a songwriter. By 1969, he’d crafted a No. 1 single for the Beatles in “Something.” “He’d written a couple before that on some of the earlier albums,” McCartney says. “They were really good. He was starting to shape up. But he’d never seemed that interested — I suppose, because John and I were kind of dominating it.”
