"She's got legs, she knows how to use them...". Here's a trivia moment. How is Portland, a small city by the sea, connected to Texas' largest city, Houston? Well, on March 3, 1977 the Cumberland County Civic Center opened its doors to just under 10,000 screaming fans to ZZ Top and their blues-inspired rock. That lil' ol' band from Houston, Billy Gibbons, Dusty Hill and Frank Beard, did a fine job breaking open those doors that night.
