 He is known for his long-running roles on "The Simpsons", his work on "Saturday Night Live", the comedy band Spinal Tap and his radio program "Le Show".
 Born in Los Angeles, California, Shearer began his career as a child actor.
 From 1969 to 1976, Shearer was a member of The Credibility Gap, a radio comedy group.
 Following the breakup of the group, Shearer co-wrote the film "Real Life" with Albert Brooks and started writing for Martin Mull's television series "Fernwood 2 Night".
Spinal Tap (stylized as Spın̈al Tap, with a dotless letter "i" and a metal umlaut over the "n") is a parody band spoofing the style of rock heavy metal groups.
 The band first appeared on a 1979 ABC TV sketch comedy pilot called "The T.V. Show", starring Rob Reiner.
 The sketch, actually a mock promotional video for the song "Rock and Roll Nightmare", was written by Reiner and the band, and included songwriter/performer Loudon Wainwright III on keyboards.
 Later the band became the fictional subject of the 1984 rockumentary/mockumentary film "This Is Spinal Tap".
 The band members are portrayed by Michael McKean (as David St. Hubbins), Christopher Guest (as Nigel Tufnel) and Harry Shearer (as Derek Smalls).
Spontaneous Combustion is an album by progressive metal group Liquid Trio Experiment, and is the result of the studio improvisations of Liquid Tension Experiment which occurred while John Petrucci was with his wife while she was giving birth.
 The trio of Mike Portnoy, Tony Levin and Jordan Rudess continued to write music during this period.
 It was released on October 23, 2007.
 A few songs from "Liquid Tension Experiment 2" were spawned from these jam sessions including "914", "Chewbacca", and "Liquid Dreams".
 The song "Chris & Kevin's Bogus Journey" is not a reference to Portnoy and Petrucci's former Dream Theater bandmates Chris Collins and Kevin Moore, but rather to the track on Liquid Tension Experiment's first album entitled "Chris & Kevin's Excellent Adventure", which is itself a reference to the band's photographer's habit of calling Mike Portnoy and Tony Levin "Chris and Kevin", even after being corrected several times.
 It is also a reference to the 1991 film "Bill & Ted's Bogus Journey", the sequel to "Bill & Ted's Excellent Adventure".
 The song "Jazz Odyssey" is a reference to the movie "This Is Spinal Tap", in which Spinal Tap experiments with an improvisational song of the same name.
