Some more videos of the Foxboro Hot Tubs shows are up on YouTube. These two, linked below, are from the Dallas show. One is a good quality video of Mother Mary with some stage banter, and the other is just a very short clip of the boys taking the stage. By thicksyrup.

There are also a couple videos from the same show of the opening band, Smoke Up Johnny [1, 2], who I thought were really good live when I saw them in New Orleans.
