"If You Knew Susie" is the title of a popular song written by Buddy DeSylva[1] and Joseph Meyer.[2] It was published by Shapiro, Bernstein & Co. in 1925. The sheet music included ukulele tabs by Richard Konter.[3] In the largely comic song, a man sings that he knows a certain woman named Susie to be much wilder and more passionate than most people realize.
The song, which was originally written for Al Jolson, became Eddie Cantor's best-known success of the 1920s, recorded on April 6, 1925[4] and the bestseller for five weeks during the year.[5] Years later, Jolson told Cantor "If I knew it was that good, you dog, I'd never have given it to you!".[6]
