In an interview in 1995, Slash would mention hiking to a show in Houston before they became famous, it was likely either this show or the one on September 16, 1987.

Here is the section about the hike to Houston:

"That, according to Slash, is exactly what "these two chicks” saw a few years back when they gave the not-yet-famous musician a lift to Houston.

“They had this car with no windshield wipers and it was pouring down rain,” the guitarist said from a tour stop with his side project, Snakepit. “Guns had just fired its bus driver while we were on a couple-day break and I went on to the next gig without them. They eventually showed up, but I was there first.”

Since this show happened back-to-back with the December 4 show, it likely wasn't this show that Slash thought about.
