'Try everything once except folk dancing and incest'. Only one person could have come up with this saying the first time round, yet at least five well known people are supposed to have done so, including Sir Arnold Bax, Sir Winston Churchill, Sir Thomas Beecham and Oscar Wilde, not to mention that good old stand-by, Anon. Does anyone know definitively who started the phrase rolling?
Attributed to so many people that the origin seems to be lost. Hopefully, whoever said it first didn't mean to try folk dancing and incest more than once!
