Rockers Green Day were forced to postpone two concerts after frontman Billie Joe Armstrong was ordered to rest his voice.
The group postponed a concert at Dayton, Ohio on Sunday night and another scheduled appearance at Nashville, Tennessee last night, citing "the illness of a band member" as the reason for the postponements.
No further details were released about how long Armstrong was ordered to rest for. Green Day are due to play the next date on their tour in Oklahoma tomorrow.
