Yes, he sat in for 2-3 songs.....The band has IMO quite a good group of musicians, and the "play off" each other very well. I forgot how small Tommy Shaw is, kinda like "Robin Trower" small. I see your Grand Prairie show on the back of my T looks like the last 3rd of their tour dates.....Our show looks like it was #3 on the tour....27 total......No opening act.......No need to tell you to have a good time, that's a given.
