Who is the artist of this 1970's song?

It's a 1970's song called "You and I". My mom wants to know who sings
it because she can't find the song ANYWHERE or remember who sang it,
but she said a girl sang it. SOME of the lyrics are: You and I, we
don't know just where we're going. You and I, more and more our love
keeps showing.
If you need more of the lyrics, just ask and I can provide more
lyrics. Also, it would be great if you have a link to the song, but if
you can't that's fine. I need the artist name, a link to the song
online, or both. Please help! Thank you.
