Who's Sorry Now? is a 1923 popular song with music by Ted Snyder and lyrics by Bert Kalmar and Harry Ruby. It was published as a waltz in 3/4 time, but Isham Jones Orchestra had a hit in 1923 with a foxtrot arrangement in 2/4 time. The tune was released as a Brunswick single (Brunswick 2438) with the A-side Swingin' Down the Lane, recorded May 4, 1923, and falls into the American dance music and jazz genre. It was popular in 1923 through several artists, including Marion Harris, Original Memphis Five, Lewis James, and Irving Kaufman. The song later became famous again thanks to Connie Francis, whose 1957 recording in 12/8 time became a breakout hit, reaching number 4 on the US charts and number 1 in the UK in 1958. The tune has appeared in films such as A Night in Casablanca and Three Little Words, and the original 1923 recordings entered the public domain in 2024.
