Well, the song "SOMEWHERE OUT THERE" is indeed one of the feature songs in Disney's An American Tale . . . in addition it is most certainly older than that. The song is available commercially through several Jazz sheet music supply houses and if you just want the lyrics, rent An American Tale.
Contrarily . . . here are the lyrics that my memory is pulling out of a performance a LONG time ago:

Somewhere, out there
Beneath the pale moonlight,
Someone's thinking of me,
And loving me tonight.

Somewhere, out there,
Someone's singing out loud . . .
Errrrrrrr, ummmmmmm.
The second verse escapes me . . . but then we go into the chorus:

And even though I know how very far apart we are
It helps to think we might be wishing, on the same bright star
And when the night wind starts to blow its lonesome lullaby
It helps to think we're sleeping underneath the same big sky

Somewhere out there,
If love will see us through.
We'll find one another,
Somewhere out there . . .
Out where dreams . . .
Come true.

I think there's more, but that's the basics.

Oh, incidentally, the song is in the first American Tale, not American Tale Two: Fivel Goes West.
