TORONTO - Oasis guitarist Noel Gallagher won't be attending the sentencing in Toronto next month for a man who attacked him onstage during a 2008 concert.

Daniel Sullivan's sentencing for assault causing bodily harm was adjourned earlier this month because Gallagher had indicated he wanted to deliver a victim impact statement in person.

But Crown attorney Ruth Kleinhenz-Neilson says Gallagher's schedule won't permit him to attend the March 23 sentencing.

"Noel has commitments in March that are culminating in a charity concert for teen cancer that he's headlining," she said, referring to the Teenage Cancer Trust in London.

"He tried to alter his schedule but others were going to be inconvenienced by that as well."

Instead of attending in person, Gallagher will provide a written victim impact statement that will be read at Sullivan's sentencing.

"Something had to give and Noel's decided to co-operate and say `that's fine'," Kleinhenz-Neilson said.

"He's going to provide a victim impact statement and I guess I'll be reading it."

Sullivan pleaded guilty to rushing onstage at the Virgin Music Festival in Toronto in Sept. 2008 and shoving Gallagher into some speakers. The British musician suffered three broken ribs.
