Brad Paisley has recorded a series of public service announcements on behalf of Mothers Against Drunk Driving (MADD). He joined MADD's National Board of Advisors in September 2003. His uncle was killed by a drunk driver before Paisley was born. The announcements are available for download on MADD's Web site. "My current single, 'Whiskey Lullaby,' like many country songs have over the years, talks about people affected by alcohol," Paisley said. "So it seems like the right thing to do -- especially now."
