A regular feature of Saturday night television in the UK, the Billy Cotton Band Show lasted well into the 1960s, by which time it was looking rather old-fashioned. He had started as a bandleader in the 1920s. Regular vocalists were Alan Breeze and Kathie Kay, and pianist Russ Conway made regular appearances.
I must admit I didn't know that he raced cars, but apparently he and David Hampshire came fourth in the 1949 British Grand Prix at Silverstone.
