"A House is not a Home"    This is a more thoughtful and mature song than many of the peppy, rock-based songs by Bert Bachrach and Hal David.  It tells of the void in a person's life when there is no one to share a house ( which is just an empty shell , no matter how extravagant without someone present to help make it a lived in  home.)
Torme is very reverential and controlled in his perforamce whoch he invests with genuine empathy and acceptance of the lyric's profound message. Rob McConnell's arrangement is quite subdued and very much in tune with the purpose of the song and the singer's  performance.
