Mark Shelton and his wife Lisa were only married in 2014, but they've known each other since the 70's. Shortly after their wedding, Lisa was diagnosed with stage 4 lung cancer. One of her bucket list requests was to see Mark impersonate Elvis like he did when they were in high school. At 400 pounds, Mark didn't feel ready to step into the King's shoes. One year and 170 pounds, later Mark put on his sequined jumpsuit and took the stage in front of two sold-out audiences.
