I thought someone might have suggested an Elvis song or 3 so how about - Love me Tender [I know it's 1956 but it's a goodie], Wooden Heart or even Are you lonesome tonight
Some suggestions, "Up where we belong" - Joe Cocker & Jennifer Warnes; "If you leave me now" - Chicago, "Unchained Melody" - Righteous Bros (no other version will do!!) and a real off the wall one here "Love rears up its ugly head" - Living Colour
