That's pretty rough stuff. Richie looked like he was fuming when his guitar failed at the start of Stranger and he never really recovered from there. Once he takes a knock he struggles to shake it off it seems.
The drummer change did them no favours either. He was all over the place. He made a few silly mistakes in the Wanted outro and it took him forever to get started on Prayer. I'm all for rock that's rough around the edges but as Supersomic said, that sounded like a 2nd rate cover band.
It's a shame as those videos were very nicely filmed and the sound was great. But hey at least Kenny Powers turned up to sing Prayer.
