The circus came to town Thursday night as Jimmy and the Reefers moved the Under The Big Top Tour to the C.W. Mitchell Pavilion in Woodlands, TX.

Notable additions to the set list this time included “Bank of Bad Habits,” “Elvis Presley Blues,” and “Tampico Trauma.” “Cowboy in the Jungle” was tonight’s final encore and Jimmy added a few new words along the way including “The Gulf is our ocean it does not belong to BP!”

The second leg of the Under The Big Top Tour will conclude Saturday with a show in Frisco, TX. You can still get your tickets now!

• Bank of Bad Habits
• Tampico Trauma

After the soundcheck, Jimmy pulled out his iPad and chatted with those in the chatroom on Ustream. He answered a couple of questions that were posted and said a few things. He mentioned that on the next leg of the tour they’d have a camera in the lawn: “Yeah this ustream thing is cool. Wait till we put the lawn gone wild camera up next leg.”
