RE: Lost media (unknown track)

Hello all

I just recently watched Buffy the Vampire Slayer (1992) for the first time and enjoyed it immensely. However, there is one thing that has been driving me nuts for a couple of days proceeding the viewing. At around the 39:40 second mark of the film, beginning the Pike/Amalyn van chase scene, there is a track that plays which is incredibly catchy and can best be described as a jangly guitar rock song. This track is not included in the film OST and I cannot find a trace of the existence of this song anywhere online despite my best efforts. The most clear and discernable line of the song can be heard at 40:22 in the movie. Does anyone else here recognize this song or have any information regarding it???
