Killswitch Engage had two very special guests join them over the weekend at their Hampton, NH show. The first was Anthrax vocalist Joey Belladona, who got up to sing Killswitch Engage's now-famous cover of Dio's "Holy Diver". The second was former vocalist, and frequent guest both on and off stage, Howard Jones the song "The Signal Fire".
Check out the footage above. Belladona shows up around the 21:30 mark, and Jones shows up around 26:10.
