Help - early 70s duet

This duet love song is titled "STAY" (I think).
Soft melody, great harmonica interlude(?).

Some lyrics:

male: "She brushes the curl from her eyes,
she drops her robe on the floor,
she reaches for the light on the bureau,
and the darkness is her pillow once more.

Refrain(?)
"How she makes me quiver,
how she makes me smile,
with all this love I have to give her,
I guess I'm gonna stay with her awhile.."


So who did this?

thanks in advance,
Larry
