Snow White and the Seven Darfs

I read a book named "Snow white and the seven dwarfs" today. It is very famous story. I like this story, and I often watched it on video when I was a child. I like Disney movie very much. There are seven dwarfs in this story. they are so cute. But I'd forgotten some story. For example, first, the queen who disguised herself as an old woman looped the belt around snow White's and bulled it tight, tighter and tighter... and she was lying. second, she tried to kill snow white use poisoned comb. I did not those stories. So I was surprised. I could know that how to say "kagamiyo kagamiyo kagamisan...". It is very famous lines. It was "Mirror, Mirror on the wall, who's the fairest of us all?" in English. I want to watch this video in English.(141words)
