According to contactmusic.com, Elvis Costello really likes his football:
"British rocker ELVIS COSTELLO angered his fans on Wednesday night (25MAY05) by watching his favourite soccer team LIVERPOOL win the CHAMPION'S LEAGUE FINAL - rather than turn up on time to his own gig. The OLIVER'S ARMY star was due to perform at Britain's University Of East Anglia, but kept his audience waiting for more than two hours in order to watch the match. And Costello further infuriated fans, by swearing at them for booing him when he finally took to the stage, prompting many audience members to walk out."
As I've said before, liking sports, especially your nation's top sport, is Advanced. It's also Advanced of him to swear at the fans.
