Just found this:
Horace Bachelor was a famous Luxembourg name. His 'Infra-draw' method promised football pool success and his producer George Harman and I were convinced there must be something in his method as he regularly won dividends himself every week. Horace did his own voice over adverts. His winning lines were always on cheaper pools (farthing a line) and often his permutation investments exceeded his winnings. But, he could always say, truthfully, 'last week I won two first dividends and six second dividends' Vivian Gale, our very posh sound technician once gave Horace the name of his (Harley Street) dentist as Horace emitted a whistle on certain words. Horace merely boarded his waiting chauffeured Rolls Royce with a smile.
He musn't have been short of a bob or two... lol
