"I Ain't Got Nobody" (sometimes referred to as "I'm So Sad and Lonely") is a popular song copyrighted in 1915. Roger A. Graham (1885–1938) wrote the lyrics, Spencer Williams composed it, and Roger Graham Music Publishing published it. It became a perennial standard, recorded many times over following generations, in styles ranging from pop to jazz to country music.
"Just a Gigolo/I Ain't Got Nobody" medley
"I Ain't Got Nobody" is best known in a form first recorded by Louis Prima in 1956, where it was paired in a medley with another old standard, "Just a Gigolo". Prima started pairing the songs in 1945 and the idea was revisited in the popular arrangement in a new, jive-and-jumping style, created by Sam Butera for Prima's 1950s Las Vegas stage show.
