All this was material for books, since most were creative folk. Obviously the columns were collected as in:
Low life, (1986) and Reach for the Ground: The Downhill Struggle of Jeffrey Bernard (1996).
Graham Lord authored, Just the One: The Wives and Times of Jeffrey Bernard
(1992), and the play Jeffrey Bernard Is Unwell (1989) by Keith Waterhouse was a hit.
High Life, Low Life (1981) was co-authored by Bernard, and details the Cat Racing story. The 1958 Great Battersea Cat Race was part of Bernard's mystique.
Concerning the setup: We agreed that if horses get three pounds for a length then cats should get an ounce for a length. ... [The cats were put on a diet, and there was a real] "red handkerchief ...[from] his pocket, which I correctly guessed to be cat racing's equivalent of the red flag at the races..."
In Just The One: The Wives And Times Of Jeffrey Bernard, we learn "cats ran around a hall way [with] a turn in it, total about 30 feet." There seems to be some controversy about who invented cat racing. That information is either lost in a boozy haze, or in the stacks.
