It is real but it's actually the Paul Oakenfold Shuffle Version #2, sampling Black and Gold​ by Sam Sparrow, B&A never worked on it! It's also from 2009, ISC had many test versions
Thanks Dazedmadonna! I know the other Paul Oakenfold demos of ISC and I think they are all great. M made the right choice to use his version. So there were just him and Mirwais remaking the song then?
