Ginny Di and her friends Tara Westmor and Lexi Dali sing Sam Cooke's "What a Wonderful World" with new lyrics from the world of Harry Potter! In the song, they are students at Hogwarts, telling us what they don't know much about. You know, alchemy, spells, etc.
So all in all, it's a Harry Potter love long. The lyrics are at the YouTube page. -via Geeks Are Sexy
