Scott Thompson, one of the feverish comic actor-writers of TV's sketch comedy program, "Kids in the Hall," performs the New York City debut of The Lowest Show on Earth, the solo piece he co-wrote with Paul Bellini, at Off-Broadway's 45 Bleecker, beginning Sept. 19.

Ted Dykstra directs Canadian Thompson in the new show about "what happens when people don't merely give into their 'lowness,' but revel in it and even indeed succeed because of it." According to production notes, "Thompson's characters make no apologies, but in an era where politics, religion, medicine and the media have all but squandered their credibility, why should they?"

The limited Off-Broadway engagement continues for six weeks, to Nov. 4. Official opening is Sept. 25. The production is presented by Clear Channel Entertainment. The Lowest Show on Earth previously played summer engagements in Montreal, Davie, FL, and Denver.

The show, with its provocatively juicy print ad campaign, is sure to lure fans of Thompson's gay-and-straight-culture spoofs on "Kids in the Hall" (which he appeared on for six years — getting exposure on the CBC, CBS, HBO and now Comedy Central). A native of Brampton, Ontario, Thompson cut his teeth in comedy in the Toronto improv group, The Love Cats. He was a series regular on "The Larry Sanders Show," a co-star in "More Tales of the City," and is a recurring character on "Providence."

Co-writer Paul Bellini's association with Scott Thompson has spanned over 20 years and has included such projects as "The Kids in the Hall," the novel "Buddy Babylon," the comedy special "Out There In Hollywood," and the rock band Mouth Congress.  On his own, Bellini has written and produced for such TV shows as "This Hour Has 22 Minutes," "The Bette MacDonald Show," "P.R.," "Yvon of the Yukon," and the film "Hayseed."  He has also recorded two CDs of original music, entitled "The Northland's Own" and "Put Paul First."  He lives in Toronto. Tickets are $35-$45. 45 Bleecker is at 45 Bleecker at Lafayette in Manhattan. Performances are 8 PM Wednesday-Friday, 8 and 11 PM Saturday and 7 PM Sunday. For ticket information, call (212) 307-4100 or for 45 Bleecker information, call (212) 529-4530.
