Toby Keith has scheduled his charity golf tournament for May 21-22 in Norman, Okla. Proceeds will benefit the Toby Keith Foundation, which is funding a 16-room guest lodge that will host pediatric cancer patients and their families on the grounds of Oklahoma University Medical Center in Oklahoma City. Completion of the facility is expected in 2012. The first night of the charity event features dinner with live entertainment and auctions, followed by a golf tournament the next day. Trace Adkins, Kelly Clarkson and Carrie Underwood are among the celebrities donating autographed memorabilia for the auction.
