Another interesting version, sung by Eddie Norwood, has an interesting verse (Birch & Backus Songs of San Francisco Minstrels, NY 187-, p. 141)

Goodbye, Darling, I Must Leave You

Oh I love a charming girl
And to her I never shall
Say or do anything that's wrong.
Now tis my great delight
To bring her here each night
Just to hear a quiet little song

Chorus:
Goodbye, darling, I must leave you.
One more kiss before I go.
I'll be here tomorrow night.
If I cannot come I'll write
Just a word or two to let my darling know.

This same version appeared in the There's Millions in it Songster (NY, 18--, p. 35); and in Jennie Engle's Bouquet of Melodies Songster (NY 1873, p. 27)
