What Evelyn Waugh (might have) said about rock band reunions

Christine McVie is rejoining Fleetwood Mac, forty four years after she first joined them and sixteen years after she left. This must be some kind of record. I'm reminded of the Father Brown line that Evelyn Waugh uses in "Brideshead Revisited".

Father Brown said something like 'I caught him' (the thief) 'with an unseen hook and an invisible line which is long enough to let him wander to the ends of the world and still to bring him back with a twitch upon the thread.'

Think he was talking about the Catholic church. It applies to rock bands too.
