Ahead of the parade, ZZ Top guitarist Billy Gibbons told ABC13 the World Series win was important for the city as it bounces back from Hurricane Harvey.
"We came in early this morning from Las Vegas and we wouldn't miss it for the world. It's really great," Gibbons said. "You've got to love it, it's a good reason to smile."
