Great Al Jolson lyrics

Everything is lovely
When you start to roam;
The birds are singin', the day that you stray,
But later, when you are further away,
Things won't seem so lovely
When you're all alone;
Here's what you'll keep saying
When you're far from home:

Mammy,
Mammy,
The sun shines east, the sun shines west,
I know where the sun shines best--
Mammy,
My little mammy,
