With his girlfriend, Vanessa Paradis, and their 9-year-old daughter, Lily-Rose, screaming in the crowd of 2,500, the Oscar-nominated actor strapped on a guitar and sang backup vocals during the power-pop group's 90-minute set.
The second annual Sheila Witkin Memorial Reunion Concert honors The Kids' late manager, who was well-known in South Florida's music scene. All proceeds from the benefit go to the Dan Marino Foundation, which funds programs for children with special needs. The band also reunited in January 2007 for the same cause.
The 45-year-old actor joined The Kids when he was a high school student in Miramar, Florida, and moved to Los Angeles with them in search of a record deal. After the band broke up, Depp decided to pursue a career in acting.
Johnny and the boys are scheduled to rock out again tonight on day two of the benefit.
