The most astonishing thing about fictional music is how effortlessly it slips out of its narrative context to join us in reality. In the case of the Monkees, the pretend rock band singing those songs became real, too. And that’s wild! Imagine if, say, an actor playing Batman decided to leave Hollywood and give vigilante justice a try. But back in the ’60s, once the Monkees’ music became more popular than their television show (a comedy about the misadventures of an unsuccessful rock band, funny enough), there was no turning back.
