I Didn't Know What Time It Was


"I Didn't Know What Time It Was" is a popular song composed by Richard Rodgers with lyrics by Lorenz Hart for the 1939 musical Too Many Girls.
Introduced by Richard Kollmar and Marcy Westcott in the stage musical, early hit versions were recorded by Benny Goodman and by Jimmy Dorsey.
It was then performed by Trudy Erwin and Richard Carlson in the 1940 film adaptation produced by RKO. The song was later interpolated into the score of the 1957 film Pal Joey, sung by Frank Sinatra, and has become a jazz standard.
