The title comes from the Alfred Lord Tennyson poem:
Sunset and evening star,
And one clear call for me!
When that which drew from out the boundless deep Turns again home.
Twilight and evening bell, And after that the dark!
And may there be no sadness of farewell, When I embark;
For tho’ from out our bourne of Time and Place The flood may bear me far,
I hope to see my Pilot face to face When I have crossed the bar.
I was blessed to have met you, Don.
