What is the name of this 70's song and the female performer?

The dots represent unknown lyrics. Here is part of one line and the chorus:

. . . . . . . . . . . leaving friends and loved ones far behind . . . . . .it all depends

It may be down some unfamiliar pathway, or cross the mountains so deep with snow
. . . . . . . . . .he'll always guide me, he'll stand beside me, let come what may
