Darkness at 3AM: Frappobeatles

I've scratched my head, and tried and tried to work out what this 3AM Girls sentence means:

Well it's only fitting... Goldfrapp have written the score for the forthcoming film Nowhere Boy, about the early life of John Lennon.

Surely the idea of Goldfrapp writing a score for a Lennon movie is intentionally picking an act which doesn't seem to be the obvious choice? Perhaps the "only fitting" is a reference to the music being recorded at Abbey Road:

We're told: "The soundtrack was recorded at Abbey Road studios, which the guys loved."

But if so, wouldn't the "fitting" remark fit better at the end?
