Turns out Magnus had a ticket for the opening match of Euro 2016 (a game your correspondent missed due to being on a working holiday in Menorca, which may account for the recent absence of posts) and had taken the trouble to pick up a song in honour of the Irons' international midfielder, who repaid the world champion's faith in him by hitting a top-notch winner a few minutes before the end.
Presumably as Magnus was singing the English-language original rather than the French version he must have picked it up off the good people who follow West Ham rather than learning it in Paris.
Anyway the clip was first shown on Norwegian television, so the total number of YouTube hits is not by any means the total number of people who have seen it, but even so, it's odd that this entertaining clip of the most famous player in chess had, in two days on YouTube, been seen by only 495 people
by the time I wrote this entry (a little after the Ireland-Sweden game finished, since you ask).
Well, not really odd. Just odd if you think, like Nigel Short, that chess
is played by hundreds of millions of people around the world.You'd have thought some of those hundreds of millions would be more interested.
