Answer:
Al Jolson
"The Jazz Singer" had its theatrical release in February 1928, but most of the studio collaborators had the chance to see a premiere on October 6th, 1927. That's why the year between brackets precedes the year of the actual theatrical release.
Al Jolson plays the title role: a musician from a traditional Jewish family, who disappoints his father by pursuing a jazz career instead of taking upon him the task of the main cantor at the local synagogue.
One of the lines spoken by Al Jolson is the famous "Wait a minute, wait a minute. You ain't heard nothing yet". According to reliable sources, Al Jolson improvised this line just after the opening credits.
Before "The Jazz Singer", Al Jolson (1886-1950) had only one role in a short movie, but he did gain fame before 1927 in several stage productions. Later on, he would star in musicals such as "The Singing Fool" (1928) and "Swanee River " (1939).
The red herrings in this question all collaborated on "The Jazz Singer": Darryl F. Zanuck was the director, Louis Silvers conducted the orchestra and Harold McCord edited the movie.
