I have a feeling that this is another recipe with a del Conte derivation, although I have cooked it so often over the years, I can't now remember what I've added to it and when. I know that people feel very strongly about anchovies, but this is guaranteed - as much as one can guarantee anything - to overcome the most squealing of prejudices. Do not think of that salty dried-up thing that curls up and dies on top of cheap takeaway pizzas: the anchovies here are mellow and, with the soft-cooked onions, have a savoury but honeyed intensity - not strong, just deep-toned and harmonious. To be on the safe side, you could just serve this as 'pasta in Venetian sauce', failing to mention the anchovy element.
