Katrina Homes Neighborhoods

Just one year ago, Jon Bon Jovi and his band rocked Oprah's world with a $1 million donation to Oprah's Angel Network for a new neighborhood in Houma, Louisiana.

"To put faces to the dream that we had together a year ago moved me like nothing else. It moved mountains emotionally. Because in light of what happened with Katrina, I felt so helpless a year ago watching television and not knowing what I could do from 1,500 miles away," Bon Jovi says.

Jon says his donation was the best $1 million he's ever spent. Between himself, his band and his football team, the Philadelphia Soul, Jon says he has built 49 homes. Still, Jon says it's everyone's responsibility to help out.

"It is America's responsibility to do that," Oprah says. "There's still thousands and thousands of people without homes."

"We have to help each other in order to keep community alive," Jon says.
