"Soily" is a song written by Paul McCartney which was performed by his band Wings, usually at the end of concerts as an encore.

This song appeared while the Band on the Run demos were recorded, with McCartney on drums. At least seven takes were recorded in 1974 at Abbey Road Studios for inclusion in the unreleased Wings film, One Hand Clapping. These takes featured drummer Geoff Britton, and several can now be found in unofficial bootlegged versions.

The song appears on the 1976 live album Wings over America and was released as the B-side on the "Maybe I'm Amazed" single in 1977. This version was recorded on 7 June 1976 at McNichols Sports Arena in Denver. A performance from One Hand Clapping can be seen on a DVD included with the 2010 remastered special edition of the Wings album Band on the Run.

The piece is notable for its bass line, which features a technically challenging chromatic run.

Sir James Paul McCartney, MBE, Hon RAM, FRCM (born 18 June 1942) is an English musician, singer-songwriter and composer. Formerly of the Beatles (1960–1970) and Wings (1971–1981), he has been described by Guinness World Records as "The Most Successful Composer and Recording Artist of All Time", with 60 gold discs and sales of over 100 million albums and 100 million singles. With John Lennon, George Harrison, and Ringo Starr, he gained worldwide fame as a member of the Beatles, and with Lennon formed one of the most celebrated songwriting partnerships of the 20th century. After leaving the Beatles, he began a solo career and later formed the band Wings with his first wife, Linda Eastman, and singer-songwriter Denny Laine.

According to the BBC, his Beatles song "Yesterday" has been covered by over 2,200 artists—more than any other song. Wings' 1977 release, "Mull of Kintyre", became one of the best-selling singles ever in the UK, and he is "the most successful songwriter" in UK chart history, according to Guinness. As a songwriter or co-writer, he is included on thirty-one number one titles on the Billboard Hot 100, and as of 2012 he has sold over 15.5 million RIAA certified units in the United States.
