Charley's quote from John Webster is from 'Westward Hoe' Act II Scene 2. It is also quite similar to one of the Apothegms of Francis Bacon (1561-1626) - "Alonso of Aragon was wont to say in commendation of age, that age appears to be best in four things, - old wood best to burn, old wine to drink, old friends to trust, and old authors to read".
Gabriel Heatter (1890-1972) was a noted US radio broadcaster, particularly famous during World War II.
