They played both Rock of Ages and Hysteria on the Lopez show, but Hysteria was recorded for an online video only and wasnt broadcast on TV. Joe's voice sounded strained at points but he didnt go out of tune once I think.

Here is the link to both vids...

I dont mind Undefeated, but the other two songs Ive only listened to once so Im not sure if that says something in itself or if I havent given them a proper chance yet.
