"Solitaire" is a ballad written by Neil Sedaka and Phil Cody. Cody employs playing the card game of solitaire as a metaphor for a man "who lost his love through his indifference"—"while life goes on around him everywhere he's playing solitaire". The song is perhaps best known via its rendition by the Carpenters. Another version by Andy Williams reached number 4 in the UK Singles Chart in 1973.

Neil Sedaka is an American singer, songwriter and pianist. Since his music career began in 1957, he has sold millions of records worldwide and has written or co-written over 500 songs for himself and other artists, collaborating mostly with lyricists Howard "Howie" Greenfield and Phil Cody.
