Havey made his national debut in 1986 on Late Night with David Letterman and made many appearances on the show throughout the 1980s and 1990s. When Letterman left NBC for CBS after not being chosen to replace Johnny Carson as host of The Tonight Show, Havey was one of several comedians considered by NBC to replace Letterman on Late Night (Conan O'Brien was chosen as Letterman's successor on the latter show).[1]
In November 1989, he was chosen by HBO Downtown Productions to host a show on The Comedy Channel (which later merged with Ha! to form Comedy Central). The show, Night After Night with Allan Havey, which initially ran for three hours nightly, presented Allan's unique stream of consciousness, celebrity interviews, news and film clips (with commentary), and unusual "on location" scenarios. Havey often recounted stories from his life, sometimes apocryphal or tongue in cheek, sometimes very real, in tandem with his breaking the fourth wall via riffing with those behind the camera, such as producer Sue Fellows or head writer Eddie Gorodetsky. Night After Night became a cult classic among fans.[2] The show also featured the sketch "Audience of One," a "Viewer Mail" segment, "Dave the Weatherman," and announcer Nick Bakay, who left in 1992, to perform the same role on The Dennis Miller Show. Night After Night ran for three years.
In a Vanity Fair interview in April 2016, Havey discussed his long-standing fear of tadpoles and Battenburg cake.
