Yngwie version rocked. No real surprise, though. He gets lots of practice with it; he works it into his solos during concerts a lot. Didn't he damn near start a riot in Brazil in 2001 or 2002 because of it? I think I remember reading that he worked it into a solo and got booed for it, so made a point to work it into every single song thereafer and the crowd got more and more unruly. Funny to see him playing it at a Marlins game though. Like playing in an empty stadium.
And Vai is unreal.
EDIT: here's a link to the Yngwie story. Guess he played it once and got booed, so came back out and played it again and had to end the set because people where throwing shit.
