Doyle had meanwhile reunited with Glenn Danzig, joining Danzig onstage during performances in December 2004 to play guitar for 30-minute sets of old Misfits songs midway through the band's setlist. It was the first time the two had performed together in over twenty years, and the first time Doyle had performed since his hiatus. Danzig called the performances "the closest thing to a Misfits reunion anyone is ever going to see". These sets featuring Doyle continued through Danzig's 2005 "Blackest of the Black" tour and 2006 Australian tour. Glenn Danzig had announced his intention to retire from touring following these, though he later contradicted this by announcing a Danzig 20th anniversary tour in 2008. In 2007, he produced Doyle's new project Gorgeous Frankenstein. Doyle later indicated that plans had been in place for the Misfits to reunite with Glenn Danzig beginning in 2002, but that Jerry Only and his manager had "put a fuckin' monkey wrench in it."
