If you’re over a certain age, there’s a good chance that every Friday night, a few seconds of rapid snare drum were your cue to grab mom her smokes and clear out. It was Dallas time. The iconic TV series still informs every ridiculous stereotype about our city almost 40 years after it premiered and a little over a quarter century since it ended. It was a prime-time soap that was silly as they came, but we tuned in every week for all the goings-ons at Southfork Ranch. Revisit that paean to opulence, big hair and serial drama as The Dallas Morning News’ Robert Wilonsky moderates a discussion with Linda Gray and Patrick Duffy, otherwise known as Sue Ellen and Bobby Ewing, at 8 p.m. Thursday, March 23. During "A Dallas Retrospective: J.R. Ewing Bourbon Presents Linda Gray and Patrick Duffy" at the AT&T Performing Arts Center, 2403 Flora St., expect insights into the legendary show and the careers of its stars. Tickets are $29 to $49 at attpac.org.
