Argh I'm annoyed I can't believe I didn't notice this until now; I knew that Wyll's animations didn't look right but I just noticed he has 4 strings= a bass guitar, and his animations are for playing bass. I swear I loaded this as bosszakk and set Wyll to guitar but it looks like this is actually a recording of "Zakk Wylde Guitar Duel (Co-Op)"
