"(I'm) Confessin' (that I Love You)" (also known as "Confessin'," "I'm Confessin'," and "Confessin' that I Love You") is a jazz and popular standard that has been recorded many times.
The song was first produced with different lyrics as "Lookin' For Another Sweetie," credited to Chris Smith and Sterling Grant, and recorded by Thomas "Fats" Waller & His Babies on December 18, 1929.
In 1930 it was reborn as "Confessin'," with new lyrics by Al Neiburg, and with the music this time credited to Doc Daugherty and Ellis Reynolds. Louis Armstrong made his first, and highly influential, recording of the song in August 1930, and continued to play it throughout his career.
Other important recorded versions in the United States were done by Chester Gaylord ( 1930), Guy Lombardo ( 1930), Rudy Vallee ( 1930), Perry Como ( 1945), Les Paul and Mary Ford ( 1952), and Anne Murray ( 1993). The song was also a number one hit for Frank Ifield in the United Kingdom and Ireland in 1963.
Dizzy Gillespie recorded a version titled "Pop's Confessin'" in which he imitated the vocal style of Louis Armstrong.
Confessin' is an album by the American jazz saxophonist John Stubblefield recorded in 1984 and released on the Italian Soul Note label.
