It seems to be based on this song Galli-Curci - Home Sweet Home.
HOME SWEET HOME
John Howard Payne,Henry R. Bishop
'Mid pleasures and palaces though we may roam
Be it ever so humble, there's no place like home!
A charm from the skies seems to hallow us there
Which seek thro' the world, is ne'er met elsewhere.
Home! Home!
Sweet, sweet home!
There's no place like home
There's no place like home!
An exile from home splendour dazzles in vain
Oh, give me my lowly thatch'd cottage again!
The birds singing gaily that came at my call
Give me them with the peace of mind dearer than all.
Home! Home!
Sweet, sweet home!
There's no place like home
There's no place like home!
