On Royal George the Third's Birth Day To-Morrow, the fourth
of June, about two o'clock, at Griffith's Tavern, London
Porter House, &c. . . 
Will be provided a good dinner, after the British mode. 
Loyal souls will then and at all times be treated with
respectful decency.
  Songs occasional be sung
  With heartfelt glee, by grateful voices,
  May peals of festive joy be rung,
  When discord shrinks, when truth rejoices.
