Getting into Stevie Ray Vaughn

There's an excellent documentary on Amazon Prime TV 
https://www.amazon.com/Stevie-Ray-Vaughan-Bluesman-1954-1983/dp/B00RHIF0NA

and one I haven't seen that's listed on the IMDb site

I lived in Austin, TX in the '70s in a house six blocks south of the Rome Inn, a former Italian restaurant that had been converted into a music club. The name didn't change because it cost too much. The regular Tuesday night band was Paul Ray and the Cobras. Paul Ray was a wonderful blues singer and his lead guitarist was a young Stevie Ray Vaughan. Stevie Ray was usually near the back of the stage with his back to the audience and I never heard him sing, that was Paul Ray's job. The cover charge was $2, a real bargain.
