Biography
Edward Gallagher (1873 - March 28, 1929) and Al Shean (real name Albert Schoenberg) (May 12, 1868 - August 12, 1949).
The comedians led separate careers in the vaudeville tradition, but it was when they teamed up that they gained popularity. Gallagher and Shean first joined forces during the tour of The Rose Maid in 1912, but they quarreled and split up two years later. They next appeared together in 1920, through the efforts of Shean's sister, Minnie Marx (mother of the Marx Brothers). This pairing lasted until 1925 and led to their fame.

Gallagher and Shean remain best known for their theme song "Mr Gallagher and Mr Shean", which was a hit in the 1922 Ziegfeld Follies. Bryan Foy, son of stage star Eddie Foy and eldest member of the "Seven Little Foys", claimed to have written the song, but it is officially attributed to Gallagher and Shean. The song endured in popularity and was regularly tweaked and updated with additional verses, so several different versions of the song are still extant. The song was recorded by Gallagher and Shean as two-sides of a 10" 78rpm record in 1922 for Victor records.
