Thousands participate in AIDS Run and Walk

October 3, 2009 (CHICAGO) The cast and crew of Jersey Boys sang the national anthem. They joined thousands of participants for Chicago's AIDS Run and Walk.

Since 2001, the event has raised more than $2 million to fund research for a cure for HIV and AIDS.

More than 3,000 people pre-registered for this year's event, that's nearly double the number from last year.
