Someone put entire setlists from that day up on YouTube. Only question mark in Anthrax's set is Joey's interpretation of 'Only'. Otherwise, they sound absolutely on FIRE. I understand the generic please the masses set list.
Mustaine really needs to take care of his voice. Take a break and see a specialist or something. He sounds downright horrible. Even I could do better and I'm an amateur singer at best. I'm sure there are mustaine voice clones out there who might serve as a temporary replacement. Might be embarrassing but I can't imagine it being more embarrassing than sounding like a cat in heat.
