'‘Regrets I’ve had a few / But then again too few to mention’, the famous song declares. It is enduringly popular: the singer did it his way. This hymn to individualism I heard broadcast the other day to us shoppers, one familiar song following another, in a place of conformity and predictability, a large supermarket, where occasionally a distracted customer, oblivious to others, will sing along or hum. I didn’t—I’m reasonably sure—in that somnambulistic state generated by supermarkets, as shoppers drift down one aisle after another, sing snatches of ‘My Way’ but I did, masked no doubt by an expressionless face, wonder about regret.'(Introduction)
