Original show tune written and composed by Cole Poter; written for the 1950 musical Out of This World
"From This Moment On" is a 1950 popular song written by Cole Porter, which has since become a jazz standard. It was originally written for the 1950 musical Out of This World, but director George Abbott dropped it from the musical before its Broadway premiere, possibly due to lackluster singing by cast member William Eythe.
