Boy In Hospital Video Chats With Steven Tyler Cole Grace is Aerosmith's number one fan. Most 7-year-olds probably only know lead singer Steven Tyler as the host of "American Idol," but Cole is considerably more mature than your average 7-year-old. Cole was diagnosed with a rare and aggressive type of brain cancer. He did not go home that day - and stayed in the hospital through the end of March. He also went through more than 20 hours worth of surgeries. While Cole was in the hospital, he made a wish: to sing "Walk this Way" with Aerosmith front runner Steven Tyler. So Hasbro Children's Hospital brought Cole and his family into a hospital room with a giant screen - and there, on Skype - was Steven Tyler.
