It wasn’t so long ago that Tesco was an also-ran in the supermarket stakes. Sainsbury’s, Safeways, even Kwik Save gave the then orange-logoed grocer a run for its money. Come the late ’70s, the store fought back with a much-trumpeted round of price slashing, plugged with a nifty little synth ditty plus till printout percussion, wherein a mixed quartet of session singers trilled a chirpy paean to ‘today’s Tescooooo’ and our solemn duty to ‘Cheggidout! Cheggidout! Cheggidout cheggidout!’ seemingly every commercial break. From that moment, retailing behemoth status was in the bag.
