I know that Yngwie turned down an offer from Deep Purple and than they got Morse instead. Yngwie said that there can´t be a Deep Purple whitout Richie who is his fav. guitar player.

And for Jason, belive me, there aren´t many folks out there that can sweep better than him. I know that guitar playn´ style took a great step from Hendrix, Purple, Sabbath, Kiss, AC/DC...stuff into more extreme playn´ stile during the early 80:s but still today it has not advanced that much. I mean there aren´t any new techniques today that didn´t exist in the eightis. Only thing that improved a lot is the sound and effect options.

And yeah, Yngwie was the man behind sweeping and he was the one who made shred and neo classical music popular. He´s more legendary than Jason no doubt about it.
