Just read a review in The Guardian of the reunion of a pop band. McFly? McBusted? Busted? Some combination of those.
That I’ve never knowingly heard the music of any of these is fine: in my 50s I’m hardly the prime market for pop music. But the G tells me that this is actually the resurrection of careers that died out a decade ago, meaning that my complete and total lack of knowledge must extend back longer than that, to when they were having their first careers.
I guess this is what they mean by the consolations of age.
