I believe this is an Irish immigrant song. It was sung by my great uncle whose mother and father came from Ireland. In 1953 when he was 93 he sang it for the family but said he hadn't heard it in 70 years. It starts out:

I'm Danny Blake from county Clare and here at your command
To sing a song in praise of home and my own native land.
I've travelled through foreign countries and in many a clime I've been,
But my heart is with old Erin where the grass grows green.

CHORUS: Then I love my native country. She's the fairest ever seen,
And I can't forget old Erin where the grass grows green.
