Rascal Flatts threw a small party at the Monroe Carell Jr. Children's Hospital at Vanderbilt in Music City for the young patients and their families last Thursday. CMT reports special guests included several Disney characters; Mickey and Minnie Mouse, Snow White and Cinderella. After performing such songs as "[sg]What Hurts The Most[/sg]" and "Fast Cars And Freedom," the trio visited hospital rooms of other children who couldn't attend the party. Rascal Flatts will play their annual benefit concert for the hospital this Friday at Nashville's Sommet Center.
