I'm Sitting on Top of the World is a 1925 American popular song composed by Ray Henderson with lyrics by Sam M Lewis and Joe Young. It was published October 7, 1925 by Leo Feist, Inc. The tune is a bright, optimistic number that became a standard of the big band era and has been recorded many times. The earliest recordings are credited to Art Gillham, the Whispering Pianist, in October 1925, with Al Jolson also recording a version that year. Notable later covers include Les Paul and Mary Ford in 1953 reaching No. 10 on the charts, The Four Aces with the Jack Pleis Orchestra in 1955, Doris Day in 1959, Aretha Franklin in 1962, Brenda Lee in 1962, and Dean Martin in 1973. The song has appeared on numerous albums and medleys, and Jolson's version has been used in Woody Allen's Zelig (1983) and in the 2005 King Kong remake. It entered the US public domain in 2021. It is not to be confused with the 1930s tune Sitting on Top of the World by Walter Vinson.
