I first met Undead Johnny several years ago when I was writing a story on The World of the Weird Monster Show, a cable show featuring "classic--and not so classic--horror and other genre films, trailers, mashups, old commercials, music videos and more combined with sketch comedy." In short, it is a horrorific good time.
I interviewed him again when I saw him at Days of the Dead a few years ago. That interview can be found at On the Beat with Undead Johnny at Days of the Dead 2015.
Actually Undead Johnny is Chad Byers. He produces and is the head-writer for TWOWMS, as well as appearing on the show as Undead Johnny.
If you're in the Chicago area, check out the show on cable. If you are not from here, check out WOWMonsterShow.com and follow the World of Weird Monster Show Facebook page for updates and more info.
