Local filmmaker Giles McCrary has produced and directed a documentary about one of the most storied clubs in all of Texas: The Cellar. You Must Be Weird or You Wouldn’t Be Here is filled with never-before-seen photos and 8mm footage of the downtown place on West Berry Street (that’s still going strong, BTW). Stevie Ray Vaughan, Jimmy Vaughan, Johnny Winters, Shawn Phillips, Bugs Henderson, John Nitzinger, and ZZ Top’s Frank Beard and Dusty Hill were just a few of the performers who played The Cellar. Comedian George Carlin also developed his shtick between sets and late at night there. You Must Be Weird will be screened as a work in progress on Sun., Nov. 21, at 2 p.m. at the Tandy Lecture Hall of the Downtown Fort Worth Library (500 W. 3rd St.). Admission is free. Must be 13 or older to attend. The screening will be followed by a panel discussion featuring music historian and writer Joe Nick Patoski and Cellar veterans and experts.
