Edwards's most famous composition, "Once in a While", became a number one hit for Tommy Dorsey and His Orchestra, and later for Patti Page (1957) and The Chimes (1961). The song is now considered a jazz standard. None of Edwards's other songs achieved the popularity of "Once in a While", and he has been called "a perfect example of a one-hit composer".
