'Could it be that John and Paul feel a song comin' on? They had plenty of time to "compose" between takes.'
I appreciate Fabulous magazine making that sound like a euphemism.
13th June 1964.
“Compose”
I mean, based on a few things in the Beatles Cartoon, gay rumours have followed John and Paul around since the beginning.
I would not be surprised, though I do think a more likely explanation is probably that quotes used to be used to emphasise something, not to say 'This is so called, like I'm quoting them, I don't believe them'
Though that leads to the question of just why you'd emphasise compose if not to also make a euphemism?
What I'm saying is that either way it sounds like they're trying to say something.
