Out of print since 2000, this out-of-character commentary track by stars Christopher Guest, Michael McKean, and Harry Shearer was originally recorded in 1994 for Criterion's Laserdisc release. It was ported to the 1998 DVD edition, along with the 20-minute "pitch reel" cut and a second commentary featuring director Rob Reiner, producer Karen Murphy, and editors Robert Leighton and Kent Beyda. Christopher Guest would not begin directing his series of improvisational comedy-documentaries until two years after this was recorded (and over ten years after the original film was completed) with 1996's Waiting for Guffman.
On this audio track (which opens with a few seconds of silence), pause just after Rob Reiner says "Hi. I'm Marty DiBergi." Get your DVD/Blu-ray/Download/Holo-Implant of the film started and pause just after the same line.
