I haven't gone back and read the whole thread, so apologies if someone else has thrown out this idea. If the Nats were to do an Expos night (or day)—and I emphasize the word "if" because I'm not taking a position yea or nay on whether to have an Expos night—then they ought to do it right. Wait until they're playing Toronto at Nats Park in whatever year the interleague matchups call for that. Do the Expos thing against Toronto. Go all-out, too—sing "O Canada" in the bilingual fashion done in Montreal. (I know the lyrics in both languages, but if I sing it, nobody will remain for the game, so bring in Bob McDonald from the Caps, as he also knows the French lyrics and sings them when the Caps play the Canadiens.)
