Watch Stevie Ray Vaughan Play Slide Guitar in 1986 Texas TV Ad

The great state of Texas launched its now-iconic "Don’t Mess with Texas" ad campaign exactly 30 years ago.

The campaign, which evolved from an extensive public-education program conducted by the Texas Highway Commission, aims to keep Texas beautiful, often hosting massive clean-up events, partnering with litter-prevention programs and more.

One of the reasons "Don't Mess with Texas" continues to thrive is its always-imaginative TV commercials, which, from the very start, have featured appearances from well-known Texans. In fact, the campaign's very first commercial from 1986 featured Stevie Ray Vaughan.

In the clip, which you can check out below (top video), a decked-out Vaughan plays a quick slide-guitar version of "I've Been Working on the Railroad" on his Strat before admonishing viewers with a simple, "Don't mess with Texas." Vaughan rarely played slide in the first place, and it's particularly unusual to see him do it in a video, even one that's only 30 seconds long.

Other commercials over the years (all of which are available to view here) have featured Willie Nelson, Matthew McConaughey, Lyle Lovett, LeAnn Rimes, Jerry Jeff Walker, Kevin Fowler and Jack Ingram. In fact, SRV's big brother, Jimmie Vaughan, appeared in a 1986 commercial with his band at the time, the Fabulous Thunderbirds. In the clip, we see that the band has changed the lyrics to their biggest hit, "Tuff Enuff," to fit the theme of the campaign. You can watch it below (bottom video).
