Scotty McCreery will sing his new single, "Water Tower Town," Thursday (March 29) on American Idol. The single will be released to country radio the same day. It marks his first Idol appearance since winning the competition in 2011. "That was my launching pad and what gave me my platform to do what I am doing now," he says. "I am looking forward to seeing some familiar faces and spending some one-on-one time with the contestants. I can't wait to give them some advice and the ins-and-outs of the competition that I learned last season."
