Veteran rocker -- and occasional Democratic fundraiser -- Jon Bon Jovi is promoting President Obama's volunteer program, United We Serve.

"We can tackle the tough challenges we face and build community through service and volunteering," Bon Jovi says in a new video. "The reality is, we're all in this together."

The video will be shown at 30 concert venues throughout the country, starting Thursday at the Staples Center in Los Angeles.

United We Serve, which Obama launched last year, promotes volunteer work on such issues as education, health, energy, the environment, and community development.

Bon Jovi told the Associated Press he spoke with Obama during the 2008 campaign about efforts to boost volunteerism.

"For me it's affordable housing," Bon Jovi told the AP. "For you it may be something else. But all these little bits make for one greater sum of the parts. It'll make for a better whole."
