Here’s a video of Stephen Tobolowsky, who’s name I didn’t recognize and had to look up to find out that I’d seen him in stuff talking about being in a high school band with a 14-year-old Stevie Ray Vaughan.
Yes, you get to hear one of the songs they recorded. It starts a little over five minutes in. It’s an electric folk song that sounds to me a little like punk rock before there was punk rock. And you could definitely tell that this Vaughan kid had something going on and might have had a future in music. Quite historically fascinating.
