Music is a great uniter, whether it's between brothers, brother and sister or even strangers. At least that's the case for 16-year-old Isaac Waddington and his little brother Jack. And while Isaac's performance moved Jack to tears, he wasn't the only one; even hard-to-please Simon Cowell was taken by Isaac's talent. So much so, in fact, that Cowell flew him to London right after finishing his school exams to sign him to his record label, Syco. In addition to singing and playing the piano, Isaac also writes his own songs, reminding Cowell of super successful Ed Sheeran. Don't expect to hear his debut album anytime soon, though; both Cowell and Isaac are keen to take time to figure out the best direction to take before recording.
