Their tour is still scheduled for 2015. Dusty Hill broke a hip and they had to cancel the end of their 2014 tour. There were driving to Chicago (Ravinia) - I had tickets to see the show.
Great picture and find! The kids were watching Back to the Future III a few weeks ago and I pointed out ZZ Top to them and told them their story. Loved their 'Legs' video - first appearance of the spinning, furry Dean guitars.
