Peg O’ My Heart gained international recognition when it was featured in the musical Ziegfeld Follies Of 1913. The song was so popular that it was the inspiration behind the 1933 film of the same name. When the Harmonicats revived the song in 1947, Peg O’ My Heart became a smash hit, surpassing its 1913 predecessor in popularity. The song has been a part of popular culture for 90 years and continues to enjoy renewed success. Peg O’ My Heart has even forayed into American television as part of a Hardees commercial. In 2000, the American Society of Composers, Authors, and Publishers (ASCAP) announced Peg O’ My Heart as one of the most-performed love songs of the 20th century.
