Chegwin was known for his off-the-cuff ad-lib style of broadcasting. He stated that no one had ever written a word for him. Chegwin's career waned in the late 1980s and 1990s, due to his alcoholism, as detailed, in his own words, in his semi autobiographical book, "Shaken But Not Stirred". In 1990, he hosted the live nightly Sky talent programme "Sky Star Search". Chegwin stopped drinking after his appearance on the Richard and Judy show "This Morning" on 5 November 1992. Chegwin's career regained speed in 1993 when he presented the "Down Your Doorstep" outside broadcast segment on "The Big Breakfast". He subsequently hosted the show and, in 1999, went on to present a revived version of the 1970s gameshow "It's a Knockout" on Channel 5. He also toured the country hosting Graham Fisher's International Knockout for corporate and charity events.
