After the band's regular gig earlier in the night at the Frank Erwin Center, Bono and Edge (with Larry laughing in the wings) end up doing one improvised jam with Stevie Ray Vaughan, Jimmy Vaughan, T-Bone Burnett and Chris Layton at an Austin nightclub. The Austin American-Statesman newspaper has published a photo of Bono and Vaughn on stage, and brief footage from the performance can be seen in the documentary, From The Sky Down.

On the 35th anniversary in 2022, Will Hodge posted an excellent in-depth write-up of the events of that night.
