"For All We Know" is a popular song published in 1934. The music was written by J. Fred Coots and the lyric by Sam M. Lewis.
The first charting versions in 1934 were by Hal Kemp (#3 on the US charts) and Isham Jones (#16). A version by Dinah Washington reached #88 on the chart in 1962. A version by Nat King Cole is also well known. The version by The Spinners in 1965 gave it a more contemporary sound.
The Rosemary Clooney version is heard over the closing credits of Dan Ireland's 2005 British film, Mrs. Palfrey at the Claremont.
