Here is what the band's website had to say: The Frontier Touring Company regret to advise that a sudden illness has struck down Green Day lead singer Billie-Joe Armstrong (food poisoning is suspected).

Although Billie-Joe was determined to perform tonight it became apparent at 4.30pm today that he would be unable to take to the stage - particularly in light of the lengthy 2.5-3 hour show the band traditionally perform.

Tonight's concert will be rescheduled to tomorrow night � Wednesday 16 December. All tickets remain valid and as allocated and do not need to be exchanged.
