Haha I remember the purple people eaters song too. Not sure who made it. Pretty funny looking back on that.
Purple People Eater - Wikipedia, the free encyclopedia
and after a little research I came up with this.
My screen name actually comes from the minnesota vikings and their defensive front four during the 70's featuring Alan Page, Jim Marshall, Gary Larsen, and Carl Eller. I'm pretty sure they were named after the song and because the vikes wear purple.
And yeah if you listen to some of Zakk's newer stuff on black label society he pulls of some crazy pinch harmonics.
