Green Day's American Idiot opened last night at the St. James Theater (click here to read our review). When we caught up with the band after the show, we wondered what it felt like to see the curtain come down on opening night. "This was the highest moment I think we've ever had as a band in the 21 years we've been around," Billie Joe Armstrong said. "And we've been pretty high," Tré Cool agreed. "Especially right now," said Billie Joe. Well, yesterday was 4/20. And they had a lot to celebrate. See more red-carpet moments in our Party Lines slideshow.
