Diana's rival from the original V as David St. Hubbins' girlfriend.
Fred Willard as a military commander at an airbase Tap performs at.
Anjelica Huston as the poor prop designer who is told to ' fuck the napkin!'note Derek: Well, you really can't fuck the napkin.
B-movie scream queens Brinke Stevens and Linnea Quigley as groupies.
Mr. Bentley from The Jeffersons as a put-upon hotel concierge/twisted old fruit.
Ed Begley Jr. was John 'Stumpy' Pepys.
Defictionalization: In spades. The actors perform in character in live shows. They've recorded three albums, made music videos, and appeared on countless radio and TV shows. They even have a feud with Marty DiBergi about their portrayal in the film, going so far as to take offense that people find the film humorous. DiBergi has at times responded to these claims. Their audio commentary on the Special Edition DVD is also fully in character, arguably constituting a movie in its own right. The song "Gimme Some Money" was even covered for a Citi Bank commercial!
The venues they play in the movie are fictitious. However, in 1989 an actual Shank Hall opened in Milwaukee. Their logo includes a miniature Stonehenge and there's a shrine to Spinal Tap in the club.
Also, amps that actually go up to eleven are now available.

In many ways, Spinal Tap has become so iconic that the boundary between real and fiction is blurred for many fans and performers of the genre, even if only to maintain The Masquerade.
Fake Brit: Harry Shearer and Michael McKean. Christopher Guest, on the other hand, has dual American-British citizenship and is now a British Baron. The accents of the cast were apparently good enough to fool British audiences.
After the release of the film, Black Sabbath's 1983 tour featured a Stonehenge set that was also marked up with the wrong measurements on the schematics (meters instead of feet, resulting in a 50' tall stone instead of a 15' tall stone).
Boy George got stuck inside a ridiculous huge prop onstage during a number.
David has a line where he'd been planning on doing a collaboration with the London Philharmonic. Something like 20 years later, Metallica came out with "S&M," a live album featuring the band playing alongside the San Francisco Symphony.
One of Spinal Tap's drummers died in a "bizarre gardening accident"; Toto drummer Jeff Porcaro was reported to have died after inhaling insecticide that he had been spraying in his garden. However, coroners later put his death down to a heart attack due to cocaine abuse.
Between 1983 and 1984, Marillion burned through three drummers in rapid succession after firing Mick Pointer before finally settling on Ian Mosley. Notably, they did this in between their first two albums, Script for a Jester's Tear and Fugazi.
In the film the band's album Shark Sandwich is given a two-word review in Rolling Stone: "Shit Sandwich." Years later, Quiet Riot's fourth album Condition Critical was given a similar two-word review in Rolling Stone: "Condition Terminal."
In 1992, the German heavy metal band Headhunter released an album titled A Bizarre Gardening Accident.
There are now guitar amplifiers that actually go to 11... and beyond. Marshall released models in the 90s with '11's on the faceplates specifically to replicate the ones in the film. Extends to some audio recording equipment too, with SSL mixers' monitor (speaker) volume settings and Pre Sonus audio I/O interfaces headphone settings.
Authentic metal legend Ozzy Osbourne is on record as saying that This Is Spinal Tap is a worryingly accurate portrayal of what it was like being a rock star in the 1980's. Specifically, although it hadn't happened to him, he describes the scene where the band get lost backstage and claims that he "could all too easily imagine that the same thing had actually happened" in real life, among other examples.
Heart's Ann Wilson said that she watched it and said, "Oh my God, that's me!"
KISS's Gene Simmons has said that the "Hello Cleveland" sequence happened to Kiss, though the specifics were different. Their dressing room was on the fourth floor, and they went down to the first floor because that's where they thought the stage would be and found nothing. They tried the second floor, nothing. Meanwhile, they could hear themselves being announced on the third floor.
Re. the comment —>David:37 people have been in this band over the years! Coincidentally, this is about the same number of personnel who have been with space rockers Hawkwind over the life of the band. And a cursory look at the Hawkwind personnel list shows a disproportionate number of these were drummers. Hawkwind's stage sets and lasers were also so ambitious they blew the fuses at many venues.
Members of Jethro Tull played a prank on their frontman, Ian Anderson, during one of their concerts. They lowered an 18" model of Stonehenge from the ceiling in mid-song, and the roadies danced around it.
Production Posse: This film originated Christopher Guest's production posse for his own mockumentary films.
The Red Stapler: Lots of real-life amps now go to 11, as well as the volume on BBC's iPlayer.
And the films rating on IMDB (well, for one film, anyway.)
Too Soon: Many Real Life musicians found this film a bit too close for comfort at the time of release.
