There’s an argument to be made that, at least early on, George Harrison was a bigger deal outside of the Beatles than he was when he was still in the band. That seems absurd, of course, since the Beatles were a one-time-only cultural phenomenon. Nothing before them was as big as they were, and nothing after them ever will be. But within the Beatles, Harrison was the Quiet One, the one always destined to be overshadowed. Throughout the band’s life, he’d made subtle musical choices to nudge the Beatles in certain directions. But he was just starting to write songs when the band was ending — or, at least, he was just starting to convince the other Beatles to record his songs — though he got a few great ones in there before the light finally blinked out. He simply hadn’t commanded the spotlight the way John Lennon and Paul McCartney had.
