DENNIE MURPHY'S DAUGHTER NELL
(Words and music by Chas. E. Baer, copyright 1895)

Just down the street a block or two lives Murphy's daughter Nell
Her hair is fair, her eyes are blue, indeed she's quite a belle
She smiles on me when e'er we meet , she has my heart and hand complete
And when work is done I start and run, my Nell to meet

Chorus
Dennie Murphy's daughter Nell waits for me after tea
She knows well, she dare not tell that she's engaged to me
But one of these days, when I get a raise, the boy that she loves so well
Will marry Denny Murphy's daughter Nell

The old man says his daughter Nell can never marry me
Says she must wed a howling swell, that's rich and up in "G"
But on his Nell I've got first call, she says its me or none at all
And last night she said we will be wed some time this fall

Found the above in the Harding Collection of American Sheet Music, of which the Irish Traditional Music Archive has a copy. There's probably a copy of the sheet itself on line somewhere - Levy collection?
Any idea what "up in G means?"
