Greetings ..

There's a song I've heard a couple times .. probably an easy one to recall for some of you. It's a duet (don't know who's singing) .. chorus is somethin like:

Despite ourselves, we're livin on the edge of a rainbow, against all odds, honey you're the big door prize, we're gonna spank our noses right off of our faces, they'll be nothing but....

Can anyone help? thx Kevin
