Rodgers & Harts' YOUR NEARER. It's a tender, ruminative song that reflects on some of the many things that remind the singer of a loved one. It concludes that  " Even when you leave me and when you're away, You'll know your nearer, For I love you so." 
It was written by Rodgers & Hart for the 1940 film " Too Many Girls" and sung by Lucille Ball in the movie. This performance features Shirley Horn, a wonderfful singer and pianist who is able to convey the essence of a song while accompanying herself on the piano.
