You don't need a drink to make music, the same way you don't need a drink to make a meal. But having a drink with a meal seems a pleaant way to eat. Perhaps not at breakfast so much.

Generally speaking folk people seem to be better at drinking without getting unpleasant - maybe that's because these days we tend to be a fair bit older than the youthful binge drinkers that are working at giving booze a bad name thse days in England. And we're probably better at looking after each other when we've had a skinful.
