Simpsons cast member Harry Shearer reprised his character Derek Smalls from the movie This Is Spinal Tap (1984).
According to Al Jean, the executives at Fox were unhappy about having Spinal Tap guest star, partially because it cost a lot of money to purchase rights to play their songs. Mike Reiss said that Fox felt that the show could have gotten a "real group" for that amount of money.
In the final scene to feature Spinal Tap, their tour bus bursts into flames after being knocked off the road. According to the writers, the scene was not in the original script and was added because they felt the band's final scene was not interesting enough.
This was the first episode to feature bus driver Otto Mann in a prominent role.
