That's possible, it wouldn't be the first time I've heard someone write something that sounds like a famous classical piece, although it's also possible that it is based on a classical piece and I'm just not recognising it. lol I actually was not familiar with Charlie Winston before this thread (although the name sounds really familiar), so it's possible there might not be a lot of info about his music out there.
Either way, good luck in your search!
