The poem read at the remembrance for Robbie Morton is by Robert Burns called Epitaph On a Friend: An honest man here lies at rest, As e'er God with His image blest: The friend of man, the friend of truth; The friend of age, and guide of youth: Few hearts like his, with virtue warm'd, Few heads with knowledge so inform'd: If there's another world, he lives in bliss; If there is none, he made the best of this.
