Soon after, on the evening of January 3, George Gershwin and lyricist Buddy De Sylva were playing billiards at the Ambassador Billiard Parlor at Broadway and 52nd Street in Manhattan. Their game was interrupted by Ira Gershwin, George's brother, who had been reading the January 4 edition of the "New-York Tribune". An unsigned article entitled "What Is American Music?" about an upcoming Whiteman concert had caught Ira's attention. The article falsely declared that George Gershwin was already "at work on a jazz concerto" for Whiteman's concert.
