Over the past three years, North Carolina coaches and fans have helped raise more than $500,000 for 5-year-old Reece Holbrook and the Pediatric Oncology Department at UNC Children's Hospital.

Later this month, country music star Vince Gill will try to add about $100,000 more.

The Grammy Award winner offered to play a benefit on April 30 at Chapel Hill's Memorial Hall after hearing the story of Reece, whose leukemia is in remission. He is the son of UNC assistant baseball coach Chad Holbrook and Jennifer Holbrook, an administrative assistant to men's basketball coach Roy Williams.

"We just get speechless, the way people continue to embrace Reece and the cause," Chad Holbrook said.

Gill learned Reece's story through friend and Vanderbilt basketball coach Kevin Stallings, who used to be on Williams' staff at Kansas and whose son, Jacob, is a UNC baseball recruit. About three weeks ago, Stallings called Holbrook and told him Gill had agreed to a concert with one provision: "He didn't want any kind of pay," Chad Holbrook said.

Tickets for the 8 p.m. concert cost $50 to $100 and are on sale at the Memorial Hall Box office (919-843-3333). Patients and hospital staff will serve as volunteer helpers at the concert. All proceeds will go to the Pediatric Oncology Department at UNC Children's Hospital. If all 1,484 seats sell out, the donation could reach $100,000.

"Reece does love music, and pretty much listens to whatever Mom and Dad are playing,'' Jennifer Holbrook said. "... The way that all this has come together is just special."

Gill's concert is the latest fund-raising effort for the hospital and a medical fund for Reece, who completed a three-year run of treatments in November.

It joins the annual Reece Holbrook Golf Classic, which will be held May 5, and the "Roy and Wanda Williams present the Reece Holbrook Sports Memorabilia Auction" on May 4.

The auction, which will include items ranging from golf outings to sporting goods (not just limited to UNC items), is open to the public and will be held at the Smith Center practice gym.
