Sum 41 singer back on stage

Deryck Whibley performed in Japan despite doc's orders

TORONTO -- Sum 41 frontman Deryck Whibley is back performing in Japan with the Canadian rock band after suffering a slipped disc in his back during a late-night bar fight (HR, Aug. 6).

The Sum 41 band website reported Whibley received treatment and performed "despite doctor's instructions" at the Summer Sonic festival in Osaka.

The Canadian rockers late last week said Whibley had been involved in an apparent bar melee in Japan, and that Japanese police had been called in to investigate.

The Canadian band last week canceled some U.S. dates on the Warped Tour after reporting Whibley had come down with a severe case of bronchitis.
