I think the problem is that this tab (like most yngwie tabs from that album) were probably written 10+ years ago. Even when I look at things published in a magazine, people had NO idea what Yngwie was doing back then. I have a great little printout from 1984 called "How To Achieve Great Speed, Like Yngwie". It boasts 20 licks straight from Yngwie's first solo guitar album, but I can't even recognize any of them because most of them are so innacurate.

So in other words: Maybe you should just learn it by ear? Its a pretty easy song.
