Duo Daft Punk did something no other French music group has done: Brought home four Grammy Awards in one night. Congratulations poured in Monday from French media, tweeters and bloggers — and even the U.S. Embassy in Paris. “See, France is capable of winning!” said commentator Jean-Jacques Bourdin on BFM-TV.
